DisplaySize 320 240
It's 4:3 screen (not quite square pixels at 720x480). Doesn't seem strange to
me.
On the monitor, if you get rid of
> "interlace" does it play properly?
Yes... I also have a progressive version of the modeline:
ModeLine "coryntscp" 28.6 720 760 824 912 480 484 492 525
I can cycle through the three of them (while playing even). The 480p
line plays correctly with Xv, and 480i(2x) doesn't... the 480i (NTSC) line I
can't check here (no TV), but I've seen this problem enough to be pretty
certain it'll be wrong too. It seems like any interlaced modeline (I've also
tried the "standard" 1024x768 at 43i line).
