Do they actually have Xv running *correctly* yet? I've been reading about various bugs for ages. If you want XvMC the only option currently seems to be to find something supported by the openchrome driver.

If these have the UVD or UVD2, they aren't documented yet, and might never be. :-( Video decoding isn't a priority in ATI FLOSS land. :-( > > I might as well go HTPC and stick an HDTV OTA ATSC / QAM tuner in > > there.

Recent GPUs can offload most of the video decode duties, but this hasn't been documented and FLOSS code hasn't been implemented yet. (Unless you can find something in the Chrome family you like.) For tuners there is the HDHomerun. Ethernet so it doesn't need a device driver or a slot. But it is digital only, no analog. Jason's cx88 driver (in ports) supports several cx88 based cards, both digital and analog. http://corona.homeunix.net/cx88wiki > > CPU will likely be... > > amd: phenom x3 8450e, athlon x2 5050e or 5600+ If it were me I'd look at Phenom II at least x2, maybe x3 or x4 depending on pricing. Decoding HD video in real time without GPU assist needs a lot of CPU. The best source of info on the state of ATI FLOSS I've found is http://www.phoronix.com/ The gang there is mostly penguins, but I'm assuming that anything that goes into x.org should work on BSD? If you're into completely documented hardware, the OGD1 price is now down to $750, but the software isn't done yet, and it is intended as a development card, not as a production graphics card.
