weird showcinema +weird sound

[Rokket]

I've got some gremlins and wonder if anybody knows the prob or a solution...

1) showcinemaborder false doesn't work for my new opening cutscene. Ignores the command. 2) In the same scene, the pitch of one of the sound files goes fast, so I slowed it, now it plays normal and then at end it goes slow.
3) stringtext for #2 never appears
4) trigger a little ways in to mission fires, does everything it should, EXCEPT it no longer plays music...

basically, I've got commands being ignored on a "computer-pick+choose" basis. I can't think of anything that could have become corrupted, I've rebooted, and this is now over 2 days.  Any ideas?

Thanks.
