LiveTV fails on clean 9.10 with basic settings that worked in 9.04

[Androktasie]

I just did a fresh format/install of Mythbuntu 9.10 on an older AMD64 box with a PVR-150 capture card and external cable box, and am no longer able to launch LiveTV. It will continuously run the change channel script for a few times before exiting back to mythfrontend's main menu. (The script runs fine from the terminal). From that point on, the tuner will appear to be in use until mythbackend is restarted.

Full steps to reproduce the bug on AMD64 or i386 are here along with a link to the captured log files.

Following more or less the same steps in 9.04 or 8.10 works just fine.

Any help in squashing this bug would be very appreciated. Thanks for helping make the world's best PVR accessible to the rest of us :)

Same behavior for me. I have a PVR-250 and PVR-350. 8.10 worked fine. I lost the ability to play tv and the ability to us my Hauppauge remote control.

Fixed the video problem. During back-end set-up, I missed the card set-up that switches the card from V4l to MPEG. The PVR series of cards are MPEG producers not V4L frame producers. Perhaps Mythtv should store this in the metadata describing the card so that the user need not remember this?

Ok - now on to the remote control.

Thanks Ken, but unfortunately my PVR-150 was already configured as IVTV MPEG, not V4L. Just tried it again tonight after a fresh install, still no luck, even after updating to the latest stable auto-build.

On the first try after a reinstall, I was greeted with this error message in MythFrontend:
"Error opening jump program file buffer"

Same problem here with another fresh install (after I doubted with the upgrade): "Error opening jump program file". In fact in the live recordings directory the file is only a few or no bytes long. Will check further with channel settings on each card, if everything is correct.

Guys,

If a solution has been found for the "error opening jump program file" error when using live tv (causes live tv to crash), please post. Thanks. Much appreciated.

This error has been documented by many at this thread at the Ubuntu Mythbuntu sub forum:

Also affecting me, though not on my PVR--150 card, that one works fine. Any time I switch to my HVR-1250, I get a black screen for about 10 seconds, then it exits out to the FE menus and gives the "error opening jump program file buffer" dialog.

There have been several reports (including http://ubuntuforums.org/showthread.php?t=1309997&page=2 ) that suggests that many people are resolving this problem going back into mythtv-setup and going through the tuner config again, possibly after enabling auto-builds (http://www.mythbuntu.org/auto-builds). Could you each please try that and report back?

MarcRandolph,

I tried enabling the auto-builds but am still having the problem. Thanks for trying.

I am affected by this bug as well. I installed to a new clean hard drive with the old one disconnected. My setup is exactly the same as my prior functioning setup on 8.04 with .21.

When the system tries to tune the tuner, it appears to be running the channel change script several times in a row. I added in an echo statement that redirected to a random file. On one channel change, the script was run in rapid succession 4 or 5 times.

I can see that the initial tune happened correctly, because there is a brief second where there is video and then after the channel change script is run a bunch more times and then the system gives up.

I modified my channel change script to just exit 0, thinking maybe the invocation is doing error checking and re-running because it doesn't receive the correct return result. No dice.

I subscribed to the autobuilds and did the big update. I am still seeing this same issue.

This is a stopper for me, as I need my PVR-500 (which is 1 x 2 PVR-150's) to work. It sucks because I bought a Revo and really want to get the new interfaces and the VDPAU. I've dropped back to .21 and I'm pretty much in a holding pattern on .22, I guess I'll take a look at the code, but I'm not fluent in c++.

Using an HD5500 and firewire on .22 worked well. I was able to import some old recordings and playback was beautiful using VDPAU.

Thanks,
Brian

I think I'm seeing the same issue on Gentoo. I'm getting the same error message and even though I can watch live TV eventually, I usually have to try twice and sometimes mythfrontend does suddenly crash. I'm using revision 25073 as packaged by Gentoo.

Is there any resolution to this widely reported problem?
