Some of the tapes that we get can be problematic so, if you want to record professionally like the TV studios do. Here is what you must do so that you do not lose the information on your tapes. Some of the bad news is that you can not recover anything from your DV tapes if nothing was recorded on them. However the way forward from now on is to record black on your tapes before shooting on them. Here is what you do. Buy a new tape or if you want to use a used tape you do the same. You insert your tape in the camcorder, with your lens cap on that means you do not take your lens cap off and then start recording. What you will be doing is laying black on your tape so that it becomes ready for recording. It means that your tape will now be recorded with black. you can then rewind and start recording with your cap off the true recording. The tapes will not then be problematic. Please let me know if this has solved your problem.

If recently recorded plays back ok, and there's no warning about low rf or head clogging problems,it seems to be electronic problem in vtr board,but usually is head problem,which is not so expensive.

Video head was dirty / clogged due to old tapes usage so it did not recorded any signal on tape and now it requires cleaning with good quality head cleaning tape to record and playback properly.

You can only view hd footage on hd devices. so if you recorded hd footage onto a tape, you will not be able to view it on a standard def camera, ie the dvx100b. The footage should not be harmed. Now if you are trying to view via p2 card over the firewire, whole new scenario.

Try Browsing the folders I Hope your footage is in one of those folders.
To Make It easier Goto Folder options click detail for folder check dates for the shooting time & open those 1st also if the camcorders timer is not set right may look in folders day earlier. Also look for big files Dvd takes lot of space.

Belive you are not being given chance to record or finalize becuse camcorder automaticaly did so. Rarely but it happens when a disk will have errors on it & when it finalzies you can lose info/footage.
Why I still prefer tape.

The problem is with the tape...Never rewind tape in the play mode for some reason it will screw it up.
And only use good tape such as...
Panasonic - MiniDV Digital Video Cassettes Model: AY-DVM80XJ

Dont use xp mode. Here are the definitions:
SP is short for Standard Play. Standard play allows you to record information onto the tape the way it was intended, with no quality loss. By default, VCRs and camcorders will record your footage as standard play. On a standard VHS tape, recording footage in SP mode will yield 2 hours of video.
LP is short for Long Play. Long play allows you to record much more information at the expense of quality. It accomplishes this by reducing the speed the tape is run through the VCR. As the tape speed decreases, the quality will also decrease. You’ll notice this effect when comparing a tape recorded at LP versus one recorded at SP, especially after years of storage. The LP tape will appear more blurred, have more tracking and color issues than tapes recorded at SP. A VHS tape recorded at LP can hold roughly 4 hours of video.
EP/SLP is short for extended play. Extended play is similar to LP, but actually provides you even more recording time. EP was primarily used to document long, continuous events without the need to change video tapes every 2 hours. Due to the fact that the video is not of optimal quality, many times this setting was not used in order to preserve the quality of your footage. Tapes recorded at EP usually are the most problematic after years of storage, displaying a wide variety of tape damage symptoms including color loss, audio loss, frame skipping, and tracking issues.

Intermittent fault? Playback of recorded footage not possible.
Even tried to check 'playback' with an older tape.

Many HDV cameras and decks are able to play and record DV as well as the higher-resolution HDV format. Additionally, many of these HDV devices will attempt to automatically change their settings to match the format of the tape that it's playing. Here are some tips for using these types of devices with Final Cut Pro / Final Cut Express.
Tip: Make explicit settings on your HDV device. Instead of using an "Auto" setting, make your own settings on your HDV device to keep the communication going between it and Final Cut Pro / Final Cut Express. This also helps Final Cut Pro / Final Cut Express keep things running smoothly with HDV devices that handle both DV-NTSC and DV-PAL.
For example, say you're using an HDV deck to capture footage from a tape that was recorded as DV-NTSC. Before capturing in Final Cut Pro / Final Cut Express, make sure that you set the deck to DV mode specifically—don't rely on Auto mode. With some devices, you may need to disconnect it from FireWire to change the mode.
For a common capture workflow, this sequence of steps can provide the best results:

1. Quit Final Cut Pro / Final Cut Express if it's open.
2. Insert your tape into your HDV deck or camcorder.
3. Use the device's menus to set it to match the format that's recorded on the tape.
4. Connect your HDV device to your computer with a FireWire cable.
5. Open Final Cut Pro / Final Cut Express.
6. Choose an Easy Setup for DV or HDV (whichever matches the format recorded on your tape).
7. Proceed to Log and Capture.

Tip: Quit Final Cut Pro / Final Cut Express before changing modes. It's generally a good idea to quit Final Cut Pro / Final Cut Express before you change the mode on your device from DV to HDV, or from HDV to DV, and then re-open the application again.
Tip: Use an Easy Setup to play back non-default HDV format footage on your HDV device. You can use Final Cut Pro / Final Cut Express to make your HDV device play back footage in its non-default HDV format. For example, maybe you have a 1080i60 HDV device and want to play back footage that was recorded as 1080i50. Or perhaps you have a 1808i50 HDV device and you want to play back footage that was recorded as 1080i60. To do this, follow these steps:

1. Connect your camera to your computer.
2. In Final Cut Pro / Final Cut Express, choose an HDV preset Easy Setup that matches the format of the tape's footage (you don't need to restart Final Cut Pro / Final Cut Express).
3. Your device's LCD display should automatically display a switch to 60 or 50, indicating the type of media that's being played.

Playing back non-default DV format footage on your HDV device You can also use your HDV device to play back footage in its non-default DV format too. For example, maybe you have a 1080i60 HDV device and want to play back footage that was recorded as DV-PAL. Or maybe you have a 1080i50 HDV device and want to play back footage that was recorded as DV-NTSC. If so, follow these steps:

1. Make sure that your device is in DV/DVCAM mode.
2. Put your device into Play/Pause mode, then open the Log and Capture window in Final Cut Pro / Final Cut Express.
3. Make sure that your device's LCD (or other readout screen) displays the same format as your tape or Final Cut Pro / Final Cut Express will misinterpret what type of device you have.

Tip: Avoid recording both HDV and DV formats on the same tape. Use separate tapes whenever you want to record in a different format. If you need to record over existing footage in a different format (for example, you have a tape with DV-PAL on it, but you want to record over it with HDV 1080i50), it's a good idea to black and code the tape, or completely record over the old footage with contiguous recording in the new format. If the tape contains even a second of, say, DV in the middle of an HDV tape (or vice versa), it could cause unexpected results later when you try to capture video from that tape.
