I've searched these forums and tried a few converters but nothing seems to be good. I used to use visual hub which up until recently was okay. Untill i tried to convert the film office space which i have as a matroska file to an mp4 for my iPhone. The film wouldnt run well and was very laggy on the iPhone. I got handbrake and that works fine for converting the film and makes .mkv's run smooth on the iPhone when converted to mp4, the only problem is that the program crashes after a while usually after converting one film. to cut a long story short! can anyone suggest some more video converters i can try that will work well with snow leopard?
