I have an apple tv with a crystalhd card model BCM970015 installed
running xbmc and the plugin mythbox. All of my hdpvr and hdhomerun
recording play perfectly. Cpu usage between 50-75%. However, I have
been unable to get things to play without a lot of stuttering on
0.24-fixes. In order to have hdmi audio I have read that one needs the
NVIDIA 100.14.19 driver and that this only compiles on ubuntu 8.04.
So, I installed the crystalbuntu image on my apple tv which sets that up
under ubuntu 8.04 with xbmc and then compiled 0.24-fixes. If I have 16
dma buffers in the crystal hd (latest git version) I get stuttering
video and audio under runs in the frontend log. I reduced that to 8,
which is what is recommended for low memory units,and then I get perfect
audio and a frozen picture. This occurs for 720p h.264 recording and
1080i mpeg2 recordings. In the audio set up I scanned for devices and
used alsa:hdmi. Changing the buffers from 16 to 8 does not seem to
Has anyone had success with this setup or got any suggestions on how to
proceed. I have compiled the latest trunk but not tried yet as that
would require upgrading my remote backend too.
