[mythtv-users] HD-PVR modprobe tx_only=1 no longer recognized

[dennismccloud at earthlink.net]

I'm having trouble getting lirc_zilog to recognize the tx_only=1 option. I previously had this working and now for some reason IR Rx is turned back on which is breaking my HD-PVR recording. With IR Rx turned on I'm getting the problem with recordings failing. If I turn off IR completely, recordings work.

I'm working on an upgrade to version 0.27 and purchased a Hauppauge HD-PVR to allow HD recording off STB. After much work, I finally got it to work.

After encountering problems with DVD burning and transcoding of the H264 recordings, I gave up on the HD-PVR and installed a HVR-1600 controller. I've got some time and am trying again to get the HD-PVR to work but for some reason I can no longer get modprobe to read the .conf file with the tx_only=1 option. Its been a month or so since the HD-PVR worked and I've updated the different software components but for some reason I can't figure out how to get the lirc_zilog option be recognized. Here is the configuration:

# uname -r
3.12.11-201.fc19.x86_64

# cat /etc/modules-load.d/lirc.conf
lirc_dev
lirc_zilog

# cat /etc/modprobe.d/lirc_zilog.conf
options lirc_zilog tx_only=1

I've tried removing the /etc/moduless-load.d/lirc.conf file to try the modprobe manually but the lirc_dev and lirc_zilog are still getting loaded by something.

Previously IR Rx was disabled with the above but now I can receive (irw) and transmit (irsend) successfully.

Here is what troubleshooting shows:

Note that previously IR Rx did not appear

I've been able to rmmod the lirc_dev and lirc_zilog modules and the HD-PVR then works OK but without channel changing.

I've been working for days to try and get this resolved without success and would appreciate any help.
