I just installed mplayer with this ppa and smplayer with this one. I put the following in my ~.mplayer/config:
vo=vdpau
vc=ffh264vdpau,ffmpeg12vdpau,
Now, mplayer works like a charm and vdpau is working, my cpu never goes above 6%. So I figured smplayer would be a nice gui for mplayer, and figured it would play the video the same way mplayer would (since it's just a frontend) but I get no video at all. What am I missing here? Do I need to do something different to get smplayer to play my mkv's?

ps x, what is the mplayer command that smplayer is running? – user23307 Feb 23 '10 at 23:21
