Something I need all the time is MPEG2 playback in Quicktime and to ability to convert from in MPEG Streamclip.
What I have found out is Snow Leopard deletes the file in library/quicktime etc.
I have followed the instructions to go back in the time machine, get the file, restore it back into the library/quicktime file
Done all that, rebooted etc....still nothing
This is kiling me today !!!!
Any help appreciated
