I've been using the attached script (since it's a script, it ought to show up 
as inline text) to encode just about everything (HD or non-HD, DVD, TV, 
whatever) to H.264.  In addition to a sufficiently current mplayer, it needs 
mkvtoolnix 2.x and vorbis-tools.   It leaves the intermediate files intact, so 
if you rip a DVD and want to save the original AC3 audio instead of transcoding 
to Vorbis, you can remux with that.  It does 2-pass encoding and tries to 
auto-detect sensible options for cropping, bitrate, interlace, etc., but these 
can be overridden.

It doesn't handle PAL video since all of my sources are NTSC or ATSC, but 
tweaking the script to include PAL support should be trivial.
