Hello, I've been looking for .mkv-to-.avi conversion software for compatible playback on my PS3. I've already tried a few freewares but they seem to be lacking in retaining the original file's quality. Now, I don't know too much about the optimal audio/video-codecs aspect of the conversion process, so if someone could give me a few pointers on that, that'd be great. Mainly though, I'd like to know which software (preferably free) is the best for the job. Thanks.
