No. I have a FlyVideo card as well and had no trouble with colour at any
resolution I tried (can't say 100% that I tried 720x576, but I think I did).
I'm using a PVR-150 now, but to be honest it's picture quality is much the
same as the FlyVideo.

What size should I be using to capture TV?


With a framegrabber the resolution should be as low as you can make it
without losing quality. In practice this means that you want to capture 576
lines but the horizontal resolution can be lower (because analog TV
horizontal resolution is pretty low). Try stuff like 480x576, 400x576 and
352x576 and see what still looks ok for you.

At no stage have I had any problems with colour on my dvb-s skystar2
> cards.


DVB cards just dump the broadcast stream to the disk. They do no processing
other than filtering the packets (if desired). So any display issues with
DVB sourced material is on the display side of the system: either X
settings, post-processing such deinterlace issues, or thte TV itself.

Cheers,
Steve
