Welcome. For 16:9 PAL the graphics should be 1024x576 and scaled
appropriately (PAL widescreen's pixel aspect ratio is 118:81). Good

Oh, that's an old version but even 1.6.2 doesn't have y4minterlace.
There are a few new tools/utilities that are only in the CVS version.
I think it'll be necessary for you to get the CVS version built.
If you have fairly recent versions of autoconf/automake/libtool the
CVS version of mjpegtools should not be too hard to build.
