I have the RF output of my STB connected to the tuner input of my PVR150. This configuration has been working nicely since R5A26 came out.
I performed a fresh (overwrite) installation of R5B7 on top of my existing working system and now find that my PVR150 receives only video static and distorted audio. The scan during installation process found channel 3, and I remembered to preset the tuner to channel 3. The fact that I have audio and it disappears when I pull the tuner input confirms that the basic sanity of my setup is fine. It's just that the PVR150 can't seem to "lock" to a good signal.
After some tweaking and no luck fixing the problem I gave up and installed 30.2. That works. So something in R5B7 has affected the ability of my < 1 year old PVR150 to receive video.
While I'm no stranger to linux, I'm relatively new to video applications on linux, so I don't really know how to troubleshoot this effectively. Any ideas? Could this be some signal level issue related to new firmware introduced in R5B7? Any obvious stuff to look at? Is there any signal debugging data produced by the PVR150 I can look at?
Thanks,
-Doug

Try upgrading just the ivtv driver on top of that 30.2 install. See the instructions at http://www.knoppmythwiki.org/index.php?page=CompileIvtv Don't miss the last paragraph!
BTW - Did you do an auto install or and auto upgrade? Sounds like the former at first glance, but the symptoms match an upgrade without dropping an recreating the tuner card definitions in mythtv-setup.
R5B7and the ivtv 0.4.3 drivers it uses haven't given me any grief with my PVR-150.

That's the strange thing. This is something I'd expect of an upgrade, but I did a clean Auto Install precisely to avoid this kind of issue. Oh well.
This is clearly a software / pvr150 firmware problem (in other words, it's not like I zapped my card in some way) since the hardware works on R5A22, A26, and 30.2.
I'll reinstall 30.2 one more time (which should work) and try to install ivtv 0.4.3 on top of that to see if that produces the same result as B7.
Thanks for the help.

I think I'm having a similar problem with my PVR150 and the tuner not being set. It is very similar to the problem that I had in this thread:
http://mysettopbox.tv/phpBB2/viewtopic.php?t=8902
but the fix I found does not work in R5B7 . I'm really at a loss on what to do now. Looks like I might have to go back down to 30.2 to get my system functional again.
Here's my grepped ivtv from dmesg:

any reason why adding: /etc/modprobe.d/ivtv Code: # Options for ivtv module
options ivtv tuner=50,2
Wouldn't work like in 30.2?

I went back to version 30.2 and the above fix worked as it did before. Something in r5b7 is messing with my ivtv

It does however have a newer version of ivtv. perhaps this is an issue for the ivtv development list. _________________ Have a question search the forum and have a look at the KnoppMythWiki.

Hmm. Wasn't trying to be insulting. I have version 0.4.3 working fine under 30.2 but can't get it to work under r5b7 following the same steps I used for 30.2 . Perhaps it is the wrong assumption that it is something in r5b7 that is causing me grief, but I can't really narrow it down to anything else.

Which video setting are you selecting in mythtv-setup? When I first set mine up, I used video0 as that is the first that pops up and also the one I used in previous editions. However, the change in the ivtv drivers seem to have bumped my 350 up to video1. Once I switched to that I got livetv again.
However, I'm still trying to figure out why the 350 won't record.

Dinki, I'm somewhat concerned about the order of your module loads, most people have to pull the ivtv line out of /etc/modules to avoid problems with the firmware not loading, this means that the ivtv stuff doesn't appear in dmesg.
Can you use the sed command shown on the wiki CheckingLogFiles page to make sure we're not misisng critical bits from the logs? I've tried to discourage people from using the grep shortcut for exactly this reason...
Also try this:
Code: grep ivtv /etc/modules
Oh and check the firmware md5sums as shown on the CompileIvtv page.

tjc, as always, thank you for your time in responding. Unfortunately I've already switched back to 30.2 and may take the route of upgrading from source to avoid the hardware issues I'm running up against. It just seems odd that using the same version of IVTV and the same steps in patching the firmware, updating the config files produces a different result. I can say that the checksums did match though.
I guess my patience hasn't been all that great lately, but I suppose having a newborn in the house can change the priorities of things.

It looks like the kernel in R5B7 moved forward from v4l1 to v4l2. You can't even build the ivtv 0.4.0 driver which uses the v4l1 API against it anymore. This could be part of the issue. Oddly both of my cards (PVR-250 and PVR-150) are behaving just fine...

Hmm. Don't really understand the ramifications. I guess it's best that I don't try to move to r5b7 then, right?
