Its a KT133A on a MSI motherboard.

It has current bios and I don't think that the BIOS will change anything
because it is not involved here.

I really don't know. May be I try a normal WinTV card with bttv and see
if this works. If this causes the same problems then we have a general
KT133 problem, if the problem is not noticable, the DVB driver may have
to be fixed.

Can you display full screen on your Duron without any damages in the
image?

I will also try to compile in the AGP support of the kernel. Maybe this
helps. BTW, I had the same problem with an old Mach64 pci card. So it
seems to be a more general problem.
