When I had these problems with the new CCCP I went back to Zoom Player - this thing still amazes me - when everything else fails it just works!
What is nice about this player - it checks your system and tells you what codecs are missing and downloads/installs them for you.
A feature like this would be REALLY nice to have in MC (17?).
MC supports some stuff natively but for the rest it relies on 3rd party codecs/filters. Too often I find MC not playing this or that (no subtitles, no audio in divx, no multichannel wav audio, etc) after an update to a new build and I have to fiddle with cccp, ac3filter, ffdshow, etc to make it work again. But Zoom Player just works no matter what.
WOULDN'T IT BE NICE IF MC INSTALL ALL NEEDED CODECS/FILTERS FOR YOU? (sorry for shouting) and check if something is missing?
I am really impressed with ZP.
Well... Installed the new pack.
MPC now crashes on mpeg2 files.
MC15 plays mpeg2 but doesn't show subtitles.
No problems with divx/xvid.
Reverted back to 09-09-09 and all is well again.
(I might have some stray filters/codecs in my system)
