[mythtv-users] HDPVR Blaster

Thu Jul 7 17:08:49 UTC 2011

Tom, I *just* got it working.  I must admit, I followed the wiki
instructions and kept failing.  I came across an irc log where Bierdo
was helping echosysp with a similar issue with the hdpvr module.  I
read along with that and noticed that the wiki makes it seem like you
can select just the pvr related modules in the v4l/.conf file to
compile, but that apparently isn't true.  I had to compile all of the
modules from the media_build tree and then install them and *then*
make sure that there weren't any duplicate modules after the install.
There were some and I had to clean those up, though I must admit, I
only cleaned up the hdvpr, lirc_zilog, lirc_dev and v4l_compat
modules.  After that, I got:

v4l2_compat_ioctl32: Unknown symbol put_compat_timespec (err 0)

in dmesg after trying to insert the hdpvr module, so I copied over my
original v4l2-compat-ioctl32.ko from my kernel tree to the module
location, ran depmod -a and then had success.  Then I modprob'd
lirc_zilog and got my /dev/lirc0 device.  Success!
