I suspect MC10 (latest beta) may have some sort of timeout set wrong, i've been playing
apple lossless, m4a, albums and often after finishing one track, it'll skip past tracks, seeming to hesitate on the next track briefly, showing the title of it, but then skipping to the next one, then perhaps skipping again till finally playing something. Seems like it tried to play it and gave up. However I then go and select the track it skipped and it'll play just fine. I might be wrong,
but my programmers intuition suspects its starting up quicktime and giving up too quickly (i'd even
had the skipped track start to play briefly before the switch to the one after, as if quicktime finally got to it but MC had already given up). I think (not positive) it was more common when i had ITunes running ripping CD in the background, chewing up CPU which would then make the quicktime start take more time.
I would be curious also if there are any plans to fix playing visualizations for quicktime format tracks so at least the track info plugins with things like lyrics, etc could show up, since obviously the tag editor reads the tags even if quicktime plays them, as does the basic display of the title, etc. (i assume they allow lyrics, bio, coverart, etc, tags).
