10.1. Troubleshooting
Q: Why do I hear TV sound, but see no video display?
A: Some VGA cards can’t support the Overlay display function. Simply select
non-overlay mode in the
Video Setting
dialog box.
Q:
Error message: Drivers have not been digitally signed in Windows
2000/XP.
A: Saying “OK” to this should continue the installation, acknowledging that you
are aware that these drivers have not
been certified by Microsoft.
Q: Why I can’t see any picture while capture?
A: Check graphics card display settings, try both 16bit and 24bit high color,
800*600 Resolution
Q: Why I can’t record sound but see the picture?
A: Please refer to
Chapter 3.6
for the correct settings
Q: What Operating Systems (O/S) does the TV Card support?
A: Now the installation CD disk only provides the WDM driver for
Windows®98SE, ME, 2000 and XP. If you seek other operating system
drivers, please see our website
Q: What can I do, when I get horizontal lines on my screen when watching
TV?
A:
1. This could have to do with the bandwidth on the PCI bus. Place the car
closest to the PCI busmaster slot or place it closest to the AGP slot, but
try to avoid PCI slot 1
1. There are some BIOS setting that you can change to get better
performance. It should be noted that you might not have all these settings.
There are also a number of various bios setups available, you should
consult the documentation that came with your system for information on
properly navigating your bios.
1. Assign IRQ to VGA (enabled, disabled)
For the PCTV to work with the graphics card this IRQ has to be
enabled.
2. PCI Master 0 Write Waitstate (enabled, disabled)
should the PCTV not function correctly, try switching this option.
Enabling write waitstates slightly slows down the PCI write access,
which might help solving problems with stability on some
motherboards. Disabling write waitstates is faster but might cause
problems.
3. IRQ Activated By (edge, level)
For modern PCI cards this option should be "level".
4. PCI Latency Timer (N)
Trying a higher value can help if you get "noise" or stripes in the TV
picture if this not related to a bad reception
