<br><span name="Christopher Neufeld" class="gD">Christopher Neufeld has been trying to track down a serious reliability issue with his HD-PVR. After much research, he discovered that his problems were due to a bug in the driver. This bug was fixed in the 3.2.11, but he runs </span>LinHES which is based on Arch Linux, which has an older kernel.<br>
<br>So, if you are having problems with your HD-PVR, and your kernel predates 3.2.11, you probably want to upgrade.<br><br>Christopher is not a member of this mailing list, and he asked me to forward this:<br><br>-------------------------------<br>
<br>
I've been having some HD-PVR discussions on IRC, and it was suggested that<br>
I post some stuff to the mailing list as it's of general interest.<br>
<br>
First, I have been having terrible reliability problems with my HD-PVR, it<br>
would get caught in a polling loop and fail to start up. I tracked this<br>
down to a race condition in the hdpvr module for the kernel I was using<br>
(2.6.39). While this race condition has been fixed in recent kernels, if<br>
you find yourself with failed HD-PVR recordings on an older kernel, and log<br>
messages that look like this:<br>

repeating every 3 or 4 seconds, check your module. In hdpvr-video.c, the<br>
function hdpvr_start_streaming(), dev->status must be set to<br>
STATUS_STREAMING before INIT_WORK sets up hdpvr_transmit_buffers. If the<br>
order is reversed, fix it and recompile.<br>
<br>
The second note is informational. If you have a free encoder on your<br>
system, it is now possible to make recordings with the HD-PVR with<br>
closed-captions available, capable of being toggled at playback time,<br>
subject to certain conditions. See<br>

Thank you.<br>
