Purchased two of these VCR/DVD recorders (for the ATSC-digital tuner) in March 2007 at Best Buy. They play PAL/region 0 out of the box. To enable region-free playback I used the CD-ROM previously made for my LG LST-3510A. Visit this link for the files to burn your disc:

http://aiwaownersnetwork.tripod.com/pages/lg/5000_series_firmware.html

Next:
--Power on the player and load the CD-ROM
--In a few moments a text box appears displaying current DVD region and a second line to change DVD region
--Press the number you wish (most likely "0") on the remote control
--Press "Enter" on the remote control
--In a few seconds the player will eject the disc. Remove the CD-ROM from the tray and power off

Upon powering on the player my region 2 and 4 DVD's play fine but Macrovision still remains.

Apparently the unit is no longer capable of reading the SACD track so it defaults to the standard cd one . You need to clean the laser head : dismantle the player to access the  head; use a can of compressed air to blow away all the dust from inside it - be especially thorough with the space between the lens and the sensor; wipe the lens with a soft q-tip; make sure the mechanism is clean and oil it.

I had the same problems with my four year Denon DVD-3910 and the only solution to it was to replace the laser unit with a new one.

There are some repair service on EBay that offer new laser units for only about 50 € and are also willing to change the laser unit for an extra charge of just 30 €.

After this replacement your Denon DVD-3910 will work fine again.

I have the Denon 2900 (about 4 years of use) and until recently, suffered from the same (growing) problem. CD's were very difficult to start/read. I recently found advice which I tried and was succesful with. It was manually cleaning the laserlens. I took away the outer housing by unscrewing all off the on top (6), side (4) and the back (2) bolts. After that I took out the top plate of the laserunit which took two very little screws taking out. Now you are looking at the cd-tray with the lens. Take a very soft and clean cloth and moisten it a little bit with clean water (be very carefull with the moistening, don't allow any waterdrop to come out of the cloth into the laserlens while cleaning! Carefully clean the lens and dry it with a dry part of the same cloth. Replace the top plate and the outer housing and the player will recognize the discs like it's new again. Good luck!

Thats how some manufacturers sell there replacement parts as they come into the country assembled. it cost let to import but more for us. i once needed a spindle motor for a unit, no replacement except the manufacturer part. Had to buy entire laser assy and thats what they bare selling you too. If you already tryed to manualy clean the lens, look on the side of the laser pick-up. it might be made by sony or a popular manufacturer go by the number printed on the label on the side or bottom of the laser assy unit itself. Good Luck

For DENON DVD-3930: In "setup", HDMI sound settings have to be "2-channel". Then SACD 5-channel output is enabled.

Have there been any changes to the systems configuration? Has there been an electrical outage or lightning strike in your area? If the answer to these are no then check the video connection to the tv ensuring both ends are secure in their ports.Ensure the tv is on the right input source for the type you are using. I know this may all seem trivial but sometimes the obvious is the easiest solution. I am assuming you have audio but no video. If you are still unable to make a picture on that tv try another one to isolate the fac t that it is the dvd player itself that is faulty.

Appears to be a software problem. Unfortunately, some blu-ray players contain software that expires, requiring you to repurchase newer, more expensive software from the manufacturer in order to continue to play blu-ray discs. Check your software for the player. No freeware blu-ray software out there.

sounds like its stoping during layer switch, if the player is old its needs to be cleaned. its best to clean it once every 20hrs or so. if you do not have a disk cleaner you should go buy one first. if the player is new return it and get the best dvd player you can buy for any amount the toshiba xde. this player is phenomenal, the best you will be amazed. no i dont work for toshiba but ever since they started making hd dvd players(i know they stopped)there players have become the best. trust me if you dont think so just return it. no harm done. if you want a blu-ray get ps3 I dont like them either but i have to admit after buying (for movies only)my third blu-ray player it is by far the best one. almost as good as the toshiba on standard dvd playback but not quite. good luck.
