Mac OS X secondary backend setup problems

As subject indicates, I am having a problem setting up the secondary backend on a mac. I start mythtv-setup and it brings up the setup menu.

I can navigate through the top level menu using the up and down arrow keys on keyboard or the apple remote. However, When I try to go into the menus from the top level, nothing apparent happens.

I did try turning on full verbose logging, and saw the keyboard actions while i was trying to maneuver to the sub menus(particularly the general menu), however the general settings menu doesn't show up. Rather, nothing appears to happen unless I press escape to get out of setup completely.

Help!

Thanks in advance!

If you are able to run the frontend, go into Settings>Appearance and
change from the OpenGL painter to Qt. Exit and now menus should work
in MythTV-Setup. I'd be interested to know if you can play back
videos with Qt selected. I can't play recorded TV (North American
broadcast recorded via HDHomerun) or movie rips (mpeg2).

Changing to Qt did indeed fix my navigation problem in mythtv-setup, Thanks!

As far as video playback when using Qt, I get sound, but no video, and the screen says Waiting... Back to OpenGL painter for Mythfrontend! I am on North American broadcast as well, using HDHR3 also.

Thanks. Where did your OS X binaries come from? osx-packager.pl,
osx-packager-qtskd.pl? Do you know which version of Qt?

Also, I'm curious about running a slave backend on OS X, if you don't
mind. Obviously, any backend could talk to the HDHR3. Why set up
the Mac as a slave as opposed to having your primary backend control
the additional tuners?

I downloaded the latest .25-fixes dmg from sourceforge for 10.7 and is dated 2012-06-05.
fixes/0.25 [v0.25.1] www.mythtv.org
Qt version: compile: 4.8.1, runtime: 4.8.1

My objective is to use the mac slave backend only when I want mythtv to transcode and I have set up a startmyth.sh and stopmyth.sh to mount nfs/start mythbackend, and umount nfs/stop mythbackend respectively.

My master backend is a lightweight AMD fusion processor with low power requirements and is configured to not transcode jobs. It suffices for all recording, and serving of video. I do not have any tuners configured on the Mac slave backend.

I have the mac do an nfs mount of the /var/lib/mythtv dir structure from the mac to the master backend to read the source mpg and write the transcode file to.

I think you only need to run the job queue; not a slave backend. Was
MythJobQueue.app in your download from sourceforge? AFAIK, a backend
must have tuners defined. Also, I don't think you have to use nfs
mounts but I really don't have any experience with transcoding.

MythJobQueue was in the download, and I did not realize that it was independent of the backend. Interesting, I will look into it.

Looks like if you are using a secondary backend, it doesn't need tuners defined; only the primary backend does..

I did try transcoding without the nfs mount, and it failed, not creating the new/updated version of the video. It did go through the motions which was interesting, just created no new video file. Using the nfs mount cured this problem.

Yes, that's what you should use.

It will run, but it's not a supported configuration. Besides,
mythjobqueue takes 1/10th the resources of a slave backend (literally):

Yes, transcoding (just like recording) requires "local" access to the
file system to write the video. We don't support writing video over the
network using MythTV's protocol. NFS provides a local view of that
remote file system, allowing you to write across the network.

Thanks! I have modded my scripts to use MuthJobQueue instead of mythbackend, and it is working fine.
