Yes, that's correct. What I meant is XvMC is a generic interface that  
myth codes to and consequently any graphics driver that supports its  
side of the interface will automatically work with myth.

Total guess but perhaps there's confusion going on because the driver  
supports XvMC on older intel graphics chips (ie 4+ years old) but not  
for the recent stuff so maybe there's a "yes I can"/"no I can't"  
thing going on depending on the application's query. Just a guess.

Anyway, the good news is last July there was a post in one of the  
xorg lists where Keith Packard, who's working on the intel drivers,  
said they were going to try to have XvMC supported on recent chipsets  
by the end of the year. Seems like there's a lot of these type of  
announcements lately but because of who made it I tend to have more  
confidence.
