If Ati would make sure when using the 780g chipset hdmi is working on all tvs and give bitstream audio support for all dts and dolby formats, then I would party with you
As noted by steelman1991, not within BluRay specs, but long before I realized there were going to be these kind of limitations, and long before anyone really understood them, I (and countless others) started encoding with x264 and used more than 4 ref. frames with 1080p encodes. Most people use 5 or 6, because that's what just about every guide tells you is the optimal setting. And with 5 or 6 ref. frames, you can't playback that material in DXVA with a L4.1 limitation. And with it taking approx 26 hours to encode a 2 hour movie in x264 at 1080p, I'd rather have a simple driver fix than have to reencode dozens of movies...
With respect to "bitstream audio support for all dts and dolby formats", well, if you're talking about 7.1 Dolby TrueHD and 7.1 DTS-HD/MA, that's just not physically possible with the 780g chipset, the technology just isn't built into the chip, it's got nothing to do with driver limitations. It's kind of like criticizing SmartCar for not being able to pull a trailer with a 20,000 lb sailboat... The hardware was never intended to do that.\
BTW, never got a chance to test the new CAT 10.4's last night due to too many beers consumed at a friend's retirement dinner. Will have to try again for sobriety tonight...
Cheers,
