anything that is ffmpeg based on Linux or windows should give you similar speeds. You can probaby even transcode it with VLC.
OK, so I installed ffmpeg along with various and sundry ancillary modules. With some tinkering and googling, I've got it to the point  where it appears to be doing something
, albeit with a surfeit of "VBV underflow" errors. My knowledge of video transcoding is clearly quite limited, so I'm wondering if anyone here might know the proper ffmpeg incantation to convert these videos into something usable on the iPod. Or, alternatively, recommend some other tool (along with the correct command line) that I can use in a batch mode, preferably on a Linux machine.
Then, maybe, I'll be able to watch the videos on the commuter train without having to haul out my notebook PC.
Thanks for any help.
 The latest command I've tried is:
ffmpeg -vcodec h264 -i LR2-06_LibraryFilter.mov \
-b 1800 -maxrate 2500 -qmax 5 -s 320x180 \
-bufsize 8192 -padtop 30 -padbottom 30 \
-acodec aac -ab 192 libraryfilter.mp4
