Broadcom Crystalhd slow performance issues.

Hi
Does anyone, of archlinux users here, have broadcom bcm70012 or bcm70015 mini pci-e device ? I have bought mine couple of days ago, and after compilation of drivers from AUR, I am very disappointed with performance. I'm using XBMC from AUR, the xbmc-git package. I had to edit PKGBUILD and add --enable-crystalhd to ./configure section. Everything compiled just fine, and I have crystalhd option in xbmc settings. Ofcourse, it is enabled.

But...
Only 720p movies are playing well. Not exactly, cause sometimes frames drop to 23 or less, but this happens rather rarely. However full hd (1080p) is just unwatchable only 7-14 fps which is realy bad, actually it is unacceptable.

My arch system is up to date, so I really don't need to tell you what is my system spec. I just want to know if anyone here have some experience with this broadcom "sh*t" and maybe can help me to make it usefull. If not, I'm selling this piece of crap to some windows user.

I have a BCM970012 myself (so the old model), in an AppleTV. Xbmc has a diagnostics overlay, so you can tell what's actually going wrong (buffering, crystalhd actually being used or not, etc.).

You should check there first and keep an eye on Xbmc's log while playing, anything crystalhd-related should pop up there.

Yes I know, and I also have bcm70012.

What I'm asking is, are you using archlinux on that AppleTV ?

It would be of little use to you if I would type all that when using it with the original Apple firmware, no? While the codebase is identical the underlying system still isn't.

I just got a 970015 mini-pcie and experience the same issue: On linux, 1080p is choppy in mplayer and vlc, but works fine on youtube (???).
On Windows OS, 1080p is smooth.
720p is smooth in any case (was unplayable on this hardware without the 970015).

Here is my install thread^^

I assume it's a linux driver/software issue since mplayer on Win is fine on the same hardware.
