The actual PAL resolution is somewhat like 768x576. (There are longish discussions
about that...) I believe that the TV card delivers something like 768x576 or 720x576.
(Or frames with 768x288.) I do not know how it is implemented, but I could imagine
that it will be faster to just divide by 2.

Perhaps your disk throughput is to low. Have you activated DMA mode?
