steve,
thatīs correct.
qt isnīt able to play nero mp4 files - no matter what you do. (as far as i know)
but with wmp9/10 -> that depends on the filters/codecs you have installed. with ffdshow installed, wmp10 plays all mp4 files without an error.
with mc10/11 -> they donīt seem to care which filters i have installed. on import mc looks if qt can play it - if not = error = no import.
why doesnīt mc try to use the installed filters? imho who cares for qt on a xp-box?
zp i.e. has no problems with mp4 after installing the needed filters.
as i said: vlc, zp and wmp work fine. only mc (which is the most imprtant one) won't work.
i also have an 3ivx-encoded-file. 3ivx is not installed right now - all apps still play that file - mc throws out an "codec not installed" error. :-(
i would be very glad, if you could "boost" mc11s video-module a little to come near to the quality of the audio-part.
if i can be of any help (testing) - please just ask...
thanks
chris
