5. Video OK / No Audio:
Make sure the audio device is "Your sound card device" in the System
Device in Settings of ComproDTV. Also, you have to select the audio
source to be "WAVE" in the System Device in Settings of ComproDTV.
Check that the sound is not muted or volume too low in the Windows
Volume Control dialog. (Double-click on the speaker icon in the system
tray.)

Sometimes updating the sound card driver from vendor or VideoMate
Vista U2800F's software from www.comprousa.com may help as well.
6. No sound on the recorded file: Please see above "Video OK / No
Audio." on the number 5.
7. Playback lags: VideoMate Vista U2800F needs CPU resources to do the
encoding. Therefore, the lags come when CPU fails to encode in real time.
Usually, VCD quality needs about 1.7 GHz CPU for recording while DVD
quality needs about 2.4G CPU for recording. Press Ctrl + Alt + Del to
check your CPU usage. If it reaches 100%, then the lag is inevitable.
8. No MPEG 4 format for recording: If you would like to record video in
MPEG-4 format, you must supply your own MPEG-4 CODEC.
Furthermore, the CODEC must be installed before using ComproDTV. In
general, you can download MPEG-4 CODEC from the following web sites.
http://www.divx.com. After you install the CODEC software, you will see
the MPEG-4 format appear in the field of recording quality.
9. TV is not clear: Sometimes the signal could be reduced by the branching.
Please make sure the cable signal is good. Try to move the computer to a
TV set and connect the cable which is being used for the TV set. Also
directly connecting the cable before the splitter may help. This problem
could also come from static. Once you connect the cable to our TV card,
the static interferes with the system. It's possible to correct this problem by
connecting a wire from the grounding of the cable to ground. Also make
sure computer grounding is good.
