Hey guys, I've got this AVI, and well I'm trying to convert it to .m4v but when I open it from Quicktime it says: The document TNA IMPACT 28.01.2010.avi could not be opened. The movie is not in a format that QuickTime Player understands. Thats how I usually convert the files to iPhone (m4v) format. I even tried using Roxio Popcorn to convert it, and it says the same exact thing like Quicktime. But when I play it with VLC it works fine ... What do you guys reckon its from ? Missing any good codecs ??
