doesn't RR use media player classic for videos? Works flawless for me out of the box.
And i use the latest winamp, been running it for MONTHS and NEVER had a single issue... but that doesn't mean they dont' exist.
If it was coded to use media player, wouldn't we lose the EQ, pre-amp and other features so awesome in winamp?
Not to mention the TV support is with winamp also, sounds like it would be a HUGE overhaul to use WMP and I just don't see that happening... and I dont' think it's necessary either personally.
