One thing the built-in smartlists have enabled me to do is track down problematic files in my 8000+ audio library. While doing the "analyze audio" thing on my files over the past week, I hit several files that cause MC problems (build 123):
1) "Blank" tracks don't play nice with MC. A common example of these are the ~20 blank tracks on Dave Matthews Band "Under the Table & Dreaming". MC just hangs on these tracks. There are also some similar tracks on a couple of jazz albums I have.
2) Tracks with high-ASCII characters are also causing problems. I have a couple of albums with French titles and track names (and the appropriate accent marks). None of these tracks play for me.
In both cases, the status display either shows "Waiting" or "Buffering". Sometimes I'll get the error that "MC cannot play any of the files in the playlist...check to make sure you aren't filtering them". A couple of times, the program just quit without any error message at all & a couple of times it "Generated Errors" so "Windows had to close the program."
Any ideas? Let me know if you need more information...
Best,
Brad
