I'm was using the ddmpeg-1.6 available at http://www.ivor.it/cle266, however, 
this had a bug in it that made me submit a patch for CVS which had the field 
order reversed. I've put up a new version of the ddmpeg library at

And attached a patch to CVS MythTV, which brings back what logically is the 
correct field order.

I've added a printout of whether you have a revision of the cle chipset, which 
the ddmpeg library will use hardware or software flip, this line should 
appear right above 'Using VIA CLE266 Hardware Decoding', and it would be nice 
if you and others report this line, and what status you have with all these 
patches and the new ddmpeg library.

I've also modified the software flipping slightly, and this appears to have 
removed the slight picture bump some have been seeing.

Remember, always include kernel and kernel patches version, xfree version, 
xfree via driver version, or else well never fix this crap :)
