Question about KWorld DVB-S 100 (DVBS100) Video Capture

1 Answer

Jerky picture I have just installed the dvbt card and using the internal aerial, it has recognised all the Freeview channels and displays them BUT.. Pictures not smooth, they move in jerks or freeze and sound mainly OK but not always. Picture strength reads 83% if this is relevant. I get good Freeview on main TV (I am near SE26 transmitter) with roof aerial but I am not sure if this is a PC problem or an aerial one. Can anyone help. RGds Roland

    Thanks for suggestions. I have done some more research and think I dived into TV too quickly and need to upgrade my PC as well.
    CPU speed is only 1150mhz and grahics card is only 16mb.

    Plan to get a better CPU and graphics card before trying asgain.

    Not sure if refresh rate is reelvant but mine is 60 mhz and could go up to 76 mhz which doesnt seem a big improvement. I did get latest KWorld drivers I think.

    Thanks again for help.

You may need to check the screens refresh rate on the monitor. How much memory on the video card? Have installed the drivers from the site of the CD? Chances are some changes have been made. You know XP has upgrades all the time. Check KWorld for the latest updates. Can you make a booster transmitter..i.e a Cantenna or something like that. Let me know what happens. Good Luck, Tim

Sky problem

Freeview has nothing to do with satellite. FreeSAT is the one that uses a satellite dish for reception. FreeVIEW is received through the aerial.

Also, don't fall for the "digital aerial" scam. I install aerials as part of my business. I've been to homes with aerials 20 years old, covered in soot from the chimney and they still pick up Freeview perfectly well. Equally, I've been to homes where the owner has bought some gold plated multi-finned "digital high gain" monstrosity that has awful reception characteristics.

If your TV aerial is okay, then just plug it in to your Freeview receiving TV and do the tuning.

If you do want Freesat then you will need a satellite dish along with a Freesat receiver.

Connecting up CRT TV, VCR, DVDR and digital box

I think the better task is (A)
You can try switch scart's!! Then try to record on DVDR or leave as it is and look out for picture on your VCR!!! If you do (B) you will lose a picture quality!
good luck

Problems on the freeview 21inch Tv Teknica from Tesco was working when we bought it 2 years ago cannot get all the channels and poor reception re installed channels many many times but does not maintain...

you may want to try changing the coaxial aerial cable that feeds the tv, these can go faulty. also if you are running a series of tvs off one aerial, you should be using an aerial booster, other wise you will get a signal drop (as displayed on your tv).
If these small things don't cure it, the set requires replaceing as the tuning card is knackered

How do I retune DMTech TV Freeview with DVD video please?

Please fallow bellows instruction to retune your TV.
Also please don’t forget that MENU BUTTON from your remote, it’s not the one in the middle of remote.
There are the other MENU BUTTON in left down bottom side.
Cannot access Digital TV and am asked for a Lock code Key?
If you cannot access the Digital TV option then conduct an EEPROM RESET as mentioned above. If you are prompted to enter a lock code key enter three / four zeros.
Alternatively when prompted to enter the lock code key conduct a FIRST TIME INSTALLATION also mentioned above.
There are two options available. The first option is to conduct a general reset that will reset all user preferences. The second option would be to conduct an EEPROM RESET. An EEPROM RESET would reset all the internal hardware.

Instructions - Please refer to your DMTECH remote control and user manual provided
1. Turn the Television ON ? Button on front of Television / Power button on remote control.
2. Make sure that you are on Analogue television by pressing the TV/DVB-T button until you see PR and the channel number selected in the top right corner of the screen, e.g. PR 1.
3. You must then Press the button labelled Display until a window titled INFORMATION is displayed on the screen.
4. Only when the window titled Information is present can you continue by pressing the digit (1) twice and then pressing the button titled LINE. If you make a mistake then press Display again to remove the window titled INFORMATION and repeat the process. (Display - 1 1 - Line)
5. Once you have successfully completed step four you will notice that a menu appears on the left of the screen. You can then select which option you want, either RESET or an EEPROM RESET using the arrow keys. To execute an instruction please use the RIGHT ARROW KEY and not the ENTER button.
Make sure you have properly conducted a FIRST TIME INSTALLATION and an AUTOMATIC SEARCH. If having done this you can try conducting a manual search in an attempt to force / lock the channel.
This will erase the DVBT tuner memory and reset the interface card. This may resolve poor channel reception, the inability to store channels or even receive certain channels.

Instructions - Please refer to your DMTECH remote control and user manual provided
1. Turn the Television ON and select digital television by pressing the button labelled TV / DVB-T located under the power button on the remote control.
2. On the remote control locate and press the button labelled Menu, found at the extreme bottom left of the remote control.
3. A Menu should now appear displaying options. Scroll down and select the option labelled SETTINGS using the ARROW KEYS and the enter key located in the middle of the remote control. On the next menu you must select INSTALLATION to move on to the next menu.
4. On this last menu scroll down to the last option labelled FIRST TIME INSTALLATION and select it pressing the enter key. You will then be prompted to delete all channels, using the left arrow key to select yes and press enter to execute. The television will reset and prompt you to commence an AUTO SEARCH. Follow these instructions to tune in channels.picture
Digital Television requires much more from existing aerial systems. Having more than one digital TV may reduce signal quality and strength depending on how the aerial system is set up. It is therefore recommended that if you decide to use more than one digital television you use a booster and or at least make sure you are using a digital ready aerial. Using an existing Aerial that is split may reduce signal strength depending on how many times it is split. Please see the diagram below. The best solution when using an existing aerial is to purchase a booster device. Aerial Splitting - Why a booster is recommended. A booster is used to apply a small current that boosts the existing signal. A booster can be purchased from all main TV/HI-FI - consumer electronic product retailers.

Freeview - No transmitter found

The signal from the communal aerial might be weak, since other people are using it, or it is experiencing interference with a power cable or something.
Try a signal booster from **** Smith or Harvey Norman, RadioShack, Tandy, Walmart etc ( I assume you are Australian - Freeview :) )
Get your own aerial, if you don't live in a concrete shoebox....

Goodmans GTV69RFDT Television had all freeview now only getting 3 channels

First ensure that the TV input is set on the Freeview channels, just in case.

Then check the antenna, when Freeview does not get all channels, it is always the aerial (antenna).

Many areas in UK have still poor reception. If you use an internal antenna, go to Argos or Currys and buy an amplified antenna for freeview, that will improve the signal.

Similar problem as you helped me solve before.

OK, I think I see the problem there.
The aerial lead from the DVDR to TV should be removed.
You should have it setup the same as the other Freeview - VCR - TV
Nutshell time:
Main aerial to Freeview input.
Loop aerial from freeview output to DVDR areial input (all this does is allow you to watch freeview, or standard both out of the DVDR)
Scart from Freeview to DVDR input
Scart from DVDR output to TV
Set DVDR to AV input mode.
Set TV to AV (whatever number you need for now won't get anything on screen unless you have the right input selected)

If you can now see the Freeview picture on the TV and change the channels with the Freeview remote then you should be set for recording.

Having the aerial and a scart lead both going to the TV is not needed.

Freeview box (Duraband)

Hi Sandra , it could be poor signal ,worth trying another box on your aerial , also the aerial lead could cause this even the one from the wall plate to the Freeview box ,if your analogue picture is snowy then I would suspect the aerial have you looked for a signal strength meter in the menu , might show how good the signal is
hope this helps
cheers John
