Thanks Stroller, that page did make interesting reading, but I have
already got widescreen working with standard videocard outputs - The
issue is that I want to use a PVR350, and I can find lots of questions
but few answers about how this card handles widescreen, or more
importantly, MIXED aspect content.
I am tempted to buy one and make it work myself - The ivtv driver and
underlying hardware seems to support all of the required scaling and
res-change calls, so I would just need to do some experiments to see if
it works how I think it does.
Regards,
Steve
