I see.  So it's basically the same as going to the menu during
playback and selecting progressive or interlaced scan.  Somehow, in
the limited testing I did, it looked very good on the 9400 but still
somewhat jerky on the 8400GS PCI.

Yeechang already asked which version handles this.  I would also like
to hear, if you know.  I'm also running 180.51, where the problem
definitely exists.
