Even 1.0pre7 is ages out of date. The guys on the MPlayer Mailing
List pretty much refuse to help anyone who is still using it because
there have been so many bugfixes and enhancements since then.
Including one or two that have to do with seeking (and other things)
in MKV files. But it's your call. Compiling from scratch isn't that
bad. You'll get tons of features you probably couldn't get otherwise
(including the ability to encode to H.264)
Part of your problem probably is that 1.0pre7 is out of date. The H.
264 upgrades to FFMPEG between now and then have been by leaps and
bounds. The support in 1.0pre7 (even try2) is a paltry offering
compared to what is available. Your problem with forcing the codec
might be that your version of MPlayer doesn't understand the codec
you're trying to use.

Well, let's just do this in one simple step:
mencoder -ovc copy -oac copy (input file).mkv -o (output file).avi
I've had some problems with SOME MKV files losing audio sync, or
screwing up the keyframes, though I believe this might just be
limited to a select set of MKV files I generated. Your milage may vary.

No problem. I've had n00bish problems before too.
