Since upgrading (reformat + reinstall) to mythbuntu 12.04 (mythtv 0.25) I've had multiple different erratic problems with my tuner card (Hauppage WinTV HVR-2250).
I have the same backend configuration (using default timings as usual, made sure I had the right input groups set up etc) as I had under 0.24 which used to work mostly OK but even under 0.24 it's never been perfect.
Even with 0.24 there seemed to be a long-standing bug around occasional failures when changing channels and/or inputs that led to occasional recordings that were just a blue screen. 0.25 is much less stable.
I have Cox cable which is (still) a mix of analog and digital channels.
Changing digital channels in live tv under 0.25 often fails and crashes back to the main menu.
I cant change analog channels at all, that alwyas leads to a crash back to the main menu, after which its about an even chance that selecting the live TV menu item shows live TV, crashes back to the main menu, or pops up a dialog saying "Irrecoverable recorder error", then another saying "frontend cant connect to the backend".
Quiting/relaunching the frontend seems the only way to fix it one the tuner has apparently locked up, which is strange, as it would indicate the error is actually stateful bug only in the frontend.
I've made sure I've updated everything to latest but with no positive effect. I have the MythTV updates repository added (via mythbuntu control centre). This post:
says a lot of bugs got fixed around live TV in -fixes. What is -fixes? Is that what I'm already picking up by including the MythTV updates repository or do I need to add another repository? (or even checkout and build my own binaries... yuk). If so, which?
The two firmware files I've installed for my HVR-2250 card are:
NXP7164-2010-03-10.1.fw (analog side)
v4l-saa7164-1.0.3-3.fw (digital side)
Can anyone else using an HVR-2250 confirm these are the right ones, as there seems to be quite a lot of other files and contradictory information around the net without anything to indicate which is actually the latest/correct/best.
Any other hints would be most welcome too.
