Troubleshooting steps
If you have problem installing or running VideoMate U90, please check the
following by step:
OS issue: VideoMate U90 has to work on USB 2.0 interface. Note only
Windows XP SP2 or Vista support USB 2.0. You are welcome to
www.WindowsUpdate.com website for the Service Pack update of Microsoft.
USB 2.0 issue: you need to check your computer has USB 2.0 or not. Usually
you will see "USB 2.0 Root Hub" device in the "Sound, video and game
controllers" section of Windows Device Manager.
Driver issue: You should see " VideoMate U90 " drivers, in the "Sound, video
and game controllers" section of Windows Device Manager. If these drivers are
not there, reinstalling the VideoMate U90 drivers can help.
Power Issue: VideoMate U90 takes power from the USB port. Note: PCMCIA
and USB hub won't provide enough power so that you have to use the kind of
PCMCIA and USB hub which has power adapter included.
Sometimes plugging in another USB port may help. Some motherboards and
notebook's USB ports do not meet the USB standard providing the standard
5V 500mA power. In these cases, VideoMate U90 will not have enough power
to work. Please contact computer vendor for the issue.
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.)
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 U90's
software from www.comprousa.com may help as well.
No sound on the recorded file: Please see above "Video OK / No Audio." on
the number 5.
Playback lags: VideoMate U90 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.
