Are you sure? I have a Hauppauge PVR-150. Do you mean YUV when speaking 
of RAW? According to ivtv-detect I should be able to get YUV data from 
/dev/video32. Unfortunately mplayer fails to play that stream too.

Why do you think that ivtv is a hack? Apparently it uses v4l's standard 
way to change channels and what would you expect from a mpeg encoder 
than a mpeg stream? The problem ist just that most v4l applications do 
not support mpeg playback while most mpeg players do not know anything 
about v4l.

Maybe ivtv could support the standard (YUV?) v4l playback, but I don't 
know if the hardware can support this and I don't want to see a mpeg 
decoder in kernel space.

Just works here.
