I did some modifications on interleaved AVI pts calculation code,
so A-V sync should be better than before, at least not worse :)
It's only for interleaved files, playing _without_ the -bps option.

If you find problems with it, please report to me, and possibly
upload first 5-10 megs of the movie.
Before doing that, please check:
- it worked before, i mean with yesterday version.
  (do NOT compare to 0.17a and stuff, maybe to 0.18pre5)


Seeking isn't fixed yet, but i'll do in the next days.
(whole AVI seeking code needs to be rewritten, too big hack now)

I'll add -bps mode autoselect, based on IS_INTERLEAVED flag in the
header. If you have files with VBR mp3, please check flags.
(it's printed by today version by default, or with -v in old versions)
If this flag is NOT set, contact me, and upload first 5-10 megz...

I've talked a lot with VirtualDub author about VBR audio syncing,
seeking, but we don't agree. He said that interleaving shouldn't be
used for sync, only -bps method. But -bps will NEVER work for VBR
files, as it means constant bitrate...
Do someone know NanDub's author contact?

I have to do more testing, and feedback from users.
