720x568 is the highest capture size, but you should
play it back (under Mplayer or other tools) as 768x576
or 4:3. This is because PAL doesn't have square
pixels..

Ive tried to capture using nvrec and ffmpegrec at a
number of resolutions and I find if I get above
352x576 (1/2 D1 or CVD resolution) I start to get
frame drops.
