This allows ComproPVR to use the correct set of
frequencies for TV tuning.
Video Format
Select the proper video format for your area from the

Additionally, each TV system uses slightly different
frequencies. Therefore, it is important to choose the
correct settings.
Aspect Ratio
Select the display screen aspect ratio, the ratio of screen
width to screen height. The default ratio is 4:3. You may
also choose the 16:9 wide-screen or custom ratios.
If you select a standard ratio, i.e., 4:3 or 16:9, the screen
will retain this ratio when you resize it. If you select a

Disk usage
The actual disk space used primarily depends on the
quality settings for recording. A higher quality setting,
e.g., DVD-quality, requires significantly more disk space

material, e.g., DV camera versus broadcast TV, and your
intended use of the recorded programming.

Driver Installation
The most common cause of problems with VideoMate
For You is incorrect installation of the driver. If you have
problems watching live TV, please check if you see the
Compro VideoMate for You in the Device Manager.
If the driver is not there, uninstalling and reinstalling the
VideoMate for You driver can help. Use the Add/Remove
Programs in Control Panel applet to uninstall the old
drivers if you see the icon. Then reinstalling the drivers
should fix this problem.
Error Code: 0x1000006
This error code generally indicates a driver installation
problem. Please uninstall and reinstall the drivers, as
described above.

Video OK / No Audio
If you can view the TV picture but you get no audio:
Check the Mute and Volume settings in the Windows
Volume Control dialog. (Double-click on the speaker icon
in the system tray.)
Check the Mute and Volume settings in the ComproPVR
Volume Control dialog. VideoMate For You needs to use
the WAVE to be the audio source.
Video is not smooth
First, make sure you have a USB 2.0 connection. For
WindowsXP users, you need to update to Service Pack
1 or above in order to use USB 2.0. USB 1.1 can only
support 4 Mbps video bit rate. With a USB 2.0 host
adaptor, you can achieve up to 15 Mbps video bit rate.
VideoMate for You needs higher than 4 Mbps video bit
rate to transfer data.
VideoMate For You uses software encoding for the live
programs and consumes a lot of CPU power. Therefore,
if your CPU usage is very high while watching TV, you
may not see the smooth video. Also, at least 1Ghz CPU
system or above is necessary for this product.
Poor video quality
Please make sure you have a strong and clear video or
TV input signal. It’s better to use the cable connecting to
a TV set to verify if this is the case.
Why cannot I choose DVD format for recording?
The suggested DVD-quality video bit rate is about 7

Troubleshooting
Mbps, which is not possible with a USB 1.1 host adaptor.
With a USB 2.0 host adaptor, you can achieve up to 15
Mbps video bit rate. So if you don’t have USB 2.0
connection, you cannot choose the DVD format for
recording.
Why cannot I choose MPEG-4 format for recording?
If you would like to record video in MPEG-4 format, you
will have to have your own MPEG-4 CODEC in order to
do that. This product does not provide MPEG-4 CODEC
in the package. In general, you can download MPEG-4
CODEC from the following website.
http://www.divx.com/
http://www.microsoft.com/windows/windowsmedia/forma
t/codecdownload.aspx
After you install the CODEC software, you will see the
MPEG-4 format appear in the field of recording quality.
Why cannot I use SAP?
SAP is an optional feature. First, please check if your
model supports SAP. If so, you can choose your audio to
SAP in the Video/Audio tab in Settings of ComproPVR.
