My experience has been with XV, I could commercial detect 1-2 shows if I
was not de-interlacing on my 2.6Ghz. When using XVMC, I could commercial
detect from 4-7 shows at once without much stuttering. I believe most
of this stuttering was more data over the bus rather than CPU because I
would see pauses even when the CPU was not maxed. Now that myth lets
you pick the # of shows to detect/transcode at once and I set it to 1,
stuttering has vanished. But again, if you're running backend and
frontend on the same system you are likely not going to be able to run
XV without stuttering, unless it's a P4 3.4 or faster. You do give up
some quality with XvMC but not much, and I recommend it for anyone who
is running a backend on a frontend.
