The 350's hardware decoder only understands mpeg2. There is
evidence that the decoder can by "short-circuited" and you can
shove a YUV stream into it as well, but driver support for
that's still in early stages of development.

You can use either the framebuffer or the ivtvdev Xfree86
driver. In either case, the CPU has to do the
decoding/decompression. People report better performance from
the ivtvdev Xfree86 driver than from the framebuff. (I've only
ever used the ivtvdev Xfree86 driver.)

It can change bit-rates and resoultions, so I'd say that's
