Ah, ok - that would indicate the .mpg file is good.

That bothers me for a ~1GHz system but it does give me an idea...

True - they haven't had a new release in a while - just occasional
small updates (I do a cvs update periodically).

I am beginning to suspect that the bitrate might be too high.

Right - that makes sense. It should be possible to do a 'make
distclean' and then run ./autogen.sh - might try that and see
what happens.

Correct - that's what I had in mind. On the other hand, if the
peak bitrate is too high that could be the cause of the playback
problems on the standalone players.
When using hardware DVD players there is a strict limit for the peak
bitrate and it's quite possible that a player's reaction to
out-of-bounds stream is to just stop playing.
Software players do not have that problem - but higher bitrate streams
use more cpu cycles to decode than lower bitrates. If mplayer comes
out with the "your system is too slow" message then that says the
bitrate is too high. Need either a lower bitrate or a faster cpu.
MPlayer does seem to use more cpu time than other players though.
Another player you can try is 'vlc' from www.videolan.org
There is another complication that can enter into the equation.
DVD players can have trouble with high bitrates on recordable and
rewriteable DVD media. The +/-R(W) media is not as reflective as
the pressed/stamped DVDs one buys/rents and that can result in players
struggling to read the data reliably from that type of media. It's
for that reason that ~8000 kbits/s is a suggested maximum when the
media is going to be recordable/rewriteable DVD.
If you mentioned the encoding parameters I've lost the mail item - I'm
curious how the .m2v file was created.
