I have about 65GBs of MST3k episodes I converted years ago from VHS tapes and TV dubs. They were encoded with S-MPEG4v2 (Microsoft).
Every video program I’ve ever used on Mac, Linux and Windows supports it including my Xbox 360 (obviously) but not a single episode will play on my WDTV Live.
Unless I’m mistaken, I swear one time long ago, I remember firing up my WDTV live (or maybe the non-Live version) and having a episode play.
Was this codec supported then removed at some point? I’d be willing to downgrade just to get this support as I really have no other choices to watch these episodes.
