I have a MythTV 0.24.2 backend (from mythbuntu - 2:0.24.2+fixes.20120314.7b992ca-0ubuntu0mythbuntu4) installed and working perfectly with both a local and remote mythfrontend. This includes live TV, scheduling recordings, playing back recordings, etc.
I have installed XBMC (2:11.0~git20120321.14feb09-0ubuntu1~ppa1~maverick) and can play back previous recordings, view the program guide, etc. This is true using both the builtin myth:// protocol and the mythbox add-on. The problem arises when I try to watch live TV.
When I attempt to watch live TV, XBMC sends over the change channel command and the channel is changed correctly on my cable box (via an IR blaster attached to the HD PVR). However, this channel change takes about 10 seconds or so to fully complete, and the HD PVR never lights up to indicate it's recording. Most of the time, the XBMC interface starts showing "working", but just stops with no indication of the failure. Sometimes I will get a playback failed indication window after the "working" disappears.
I've convinced myself that this is 100% attributed to the amount of time it takes for the channel change to complete. If I do either of the following, Live TV works fantastic in XBMC:
- Change the change channel routine within mythsetup to just /bin/true. Obviously, the selected channel doesn't work, but the current channel on the box is played back perfectly.
- Change my channel script to just change to a single digit hard-coded channel. This brings the change channel time way down, but is obviously less than useful.
Is there some way to increase the timeout that XBMC will wait for a myth video source? I've tried trimming my change channel script down, but I can't seem to get it fast enough to make live TV work. I've tried messing with LIRC gap times, etc, but I can't seem to get it short enough.
Thanks for any assistance.
