Could be a Macrovision (or similar) protected signal? Macrovision works
by adding extra sync pulses in the wrong places - the idea being that your
TV will ignore a sync pulse it isn't expecting but a VCR will get
confused. Maybe you're getting a Macrovision signal and it's confusing
your TV card. </blindguess>
Alternatively, maybe you have the tuner set to the wrong TV standard (e.g.
NTSC instead of PAL)...
