Live TV issues with 0.25 and HD-PVR

There seem to be some major regressions with live TV in 0.25, or at least with my HD-PVR. With 0.22-0.24 there were lots of issues; slow channel changes, occasional drops, and a rare lockup, but for the most part it worked fine 90%+ of the time. Recordings worked 99.99% of the time. After upgrading to 0.25 records all seem to work fine as before but live TV is HORRIBLE, it maybe works 10% of the time. Starting live TV or attempting to change channels I get a bunch of "error opening jump program file buffer" errors. Backend logs show a generic "MPEGRec(/dev/video0): Device error detected", "DevRdB(/dev/video0): Poll giving up 2".

I DO NOT use the HD-PVR's IR functions, I have a separate IR receiver/transmitter that works flawlessly so no need. I had been using the 1.5.7 firmware but since I'm running Fedora 16 /w the 3.3.5 kernel I decided to try 1.7.1. It seems work about the same so far (no color issues with the 3.3.5 kernel drivers).

I assume I am not the only one seeing this, anyone have any ideas what might be going on or how I can troubleshoot this maybe a little further? I tried looking for bug reports but that was useless.. way too common an issue for a bunch of reasons.

Are you trying to watch livetv on the backend or a remote frontend I
have seen some issues with remote frontend + live TV + HD-PVR.

I wish I never moved up to .25. LiveTV on my HDPVR's is 100% failure for me (1080i). I'm hoping to test 720p, but it'll be awhile.

I ended up switching to firewire, which has it's own set of problems. .25 was a bad upgrade.

Out of curiosity, did you upgrade *just* MythTV, or did you also
upgrade your entire Linux distribution including the kernel?

I'm just trying to understand whether the perceived regression is
entirely Myth, or whether driver updates could be contributing.

Are you actually using 0.25? If so, that's likely your problem. You
should be using (current) 0.25-fixes.

I had a similar, very frustrating experience on upgrade to 0.25-fixes with
both an HR-1600 and an HDHR3-US.

I too gave serious consideration to down grading back to 0.24 for all the
reasons you mentioned and was very confused by some posters saying 0.25 was
great for livetv and others saying it sucked.

Then I completely reinstalled my inputs (HR-1600 and HDHR3-US) and that
immediately fixed the problem. Now 0.25 is the best live tv experience
with Myth we have ever had.

So if you have not already done so, completely remove (Delete All Cards)
your HDPVR and reinstall from scratch.

I hope you have the same good results I have had.

Cheers,
Dave

PS: The HDHR3-US was a new purchase from Woot for $75 US. (Thanks to the
OP for that tip!). And I see now what a difference new technology can
make. The HDHR is better all around (more sensitive, fast at channel
changes etc).Myth is a much more enjoyable experience now. The purchase of
the HDHR was that caused me to reinstall all the TV capture devices.

Re: Live TV issues with 0.25 and HD-PVR [In reply to]

I'm running 0.25 fixes, specifically the rpmfusion packages 0.25-6. My distro wasn't changed any, I ran 0.24 on Fedora 16 fine. Also.. this happens on both local and remote frontends, it seems to make no difference which one I'm using as the issue is identical on both (and I'm on an all 1Gbit network so performance there should be fine).

Re: Live TV issues with 0.25 and HD-PVR [In reply to]

Thanks, I'll try that. My HDHR (original 2 tuner model) seems to has survived the upgrade fine and I've never had a single Live TV or recording issue using it... Too bad I need the cable box to get the rest of my channels!

My upgrade came with a Mythbuntu 11.10 to Mythbuntu 12.04 upgrade.

Re: Live TV issues with 0.25 and HD-PVR [In reply to]

So deleting and and re-adding all my capture cards (and truncating the capturecard table to reset the cardid auto incrementing key back to 1, hate odd numbering tuners) I see major improvements in Live TV with my HD-PVR. I won't call it solved just yet but all my tests so far have been successful. I was able to get into live TV without an issue and all my channel changes including SD, 720p, and 1080i channels changes (and back) worked without getting dropped once. Channel changes were also noticeably much faster. I'm assuming that's mostly due to the new 1.7.1.30059 firmware I loaded along with the 3.3.5 kernel with required driver improvements.

So next question is why? There are two things that I can see that changed: 1. The timeout value was previously set to 3000, re-adding it defaulted to 12000, 2. I changed from RCA sound to SPDIF (I'd switched long ago because of some channels occationally dropping sound long ago, seems ok now). I really don't see what else deleting could possibility fix, it's just a few DB records being deleted and re-added which should make zero difference. Is there something else I'm missing?

FWIW: I tried 0.25 (for the nth time) again this past Saturday and had
the same issues. The only thing that was upgraded was MythTV. Deleted
all capture cards, and recreated. Ended up reverting the upgrade within
the day. Running 2x HD-PVR and 1x HVR1600 (analogue side only - no OTA
worth mentioning up here, and Rogers has encrypted everything worth
mentioning).

Cheers,

Andrew.

Re: Live TV issues with 0.25 and HD-PVR [In reply to]

One thing you may want to try is upgrading the firmware on your HDPVR.
I am not sure when the change happened but LiveTV certainly used to
work fine changing channels for me with the HDPVR and then stopped
producing similar errors to those mentioned here. Eventually i
tried to figure out where the issue happened but at the end of the day
upgrading the firmware fixed the problem. Note upgrading to the
latest firmware may cause colorspace issues for you if you are not
running a 3.3 or higher kernel. The ticket documenting my issue is
at: http://code.mythtv.org/trac/ticket/10741# may be worth a try.
Obviously at some point mythtv (or certainly could be a kernel driver
issue as over time that was also upgraded ) stopped working well with
livetv and it for me but the firmware definitely fixed it.
