I haven't found the difference to be as large as some people said.
The main benefit is the reduced CPU load. Right now there are downsides
to VDPAU on an underpowered system -- the OSD will cause stutter in the
video if you use any of the advanced deinterlacers even on 480i, at
least as of 3 weeks ago.
It also is less tolerant of errors in your recording which is an issue
with stuff recorded off the air, and even some firewire recordings which
do drop packets from time to time.
