recording problem with PVR 250

I am running the PVR 250 with the ivtv driver. 0.10 worked perfectly.

I just installed v0.11 and I am getting this problem. When I try to
record something, it seems to work OK, but the resulting nuv file has no
video or audio (just black screen). It does increase in size, however.

Though if, during the recording, I run 'test_ioctl -p 4', and then watch
the resulting .nuv file, I can see that the black screen changes to
normal video and audio at the point I ran test_ioctl. It's as if mythtv
is not initializing the tv card correctly.

I'll note that I can watch TV normally if I run 'test_ioctl -p 4' after
starting mythbackend. (Only have to do that once and I'm good forever)
I can change channels normally to. It's just the act of recording which
seems to generate the problem.

It's definitely related to the new release, because I can always revert
to v0.10, and get normal operation (Though even with that one, I always
have to 'initialize' the tv tuner after starting mythbackend as
described above). But I'd like to use 0.11 for the new features.

Please help,

Dana

Sounds like you upgraded MythTV, but didn't upgrade your ivtv drivers.
You need the newer ivtv drivers for things to work right under MythTV
0.11. Search the mail archive, tons of people had this problem.

I just upgraded my ivtv drivers to CVS-latest, and reloaded them. I am
still getting the exact same problem. Anyone have other ideas?

Who else had this problem? I checked before I initially posted, but
didn't see anything that matches this.

Go through /lib/modules/your-kernel and its sub-directories. Delete (or
rename) any msp3400, tuner and ivtv modules you find. Reinstall from
CVS. There's a good chance the wrong module is getting loaded. The new
one might not have actually overwritten the old one, or it may be in a
different directory, and the older one is getting first preference...

I did, among many others. The main problem is the lack of audio in
scheduled recordings. Now that I think about it, I suppose your problem
does sound a bit different (w/the no video thing), but you definitely
needed to upgrade the ivtv drivers anyway.

Try looking in your mythbackend log for anything that might shed some
light on the situation.

Also, does live TV work? You only mentioned problems w/recordings...

Re: Re: recording problem with PVR 250 [In reply to]

I think I figured out my problem, but I don't know how to fix it. When
I start mythbackend, I noticed something in my ivtv log (syslog) -->

Aug 28 10:28:00 localhost kernel: saa7115[0]: decoder set input (5)
Aug 28 10:28:00 localhost kernel: saa7115[0]: now setting Composite
input
Aug 28 10:28:00 localhost kernel: saa7115[0]: decoder set norm NTSC
Aug 28 10:28:00 localhost kernel: saa7115[0] set audio: 0x02

It is setting the input to Composite 5, even though I have set this to
Composite 4 in mythsetup. Now I realize the reason I always had to run
test_ioctl after starting mythbackend, was that test_ioctl would set the
tuner back to Composite 4. Now my problem is, how do I get mythtv to
stop setting the incorrect input?

Re: Re: recording problem with PVR 250 [In reply to]

Now I've fixed it! I simply had to change the Input Source in the setup
to TV Tuner instead of Composite 4. In MythTV 0.10 I had was able to
use Composite 4. For 0.11 I have to use Tuner 0. Don't ask me why.

Re:Re: recording problem with PVR 250 [In reply to]

I had a similar problem until I understood the setup screens properly. I
expect you've got them set up the same way I had initially.

It's setting up "Video Sources" and "Input Connections" properly.

Video Sources is only a place to make a "friendly" name for an input
connection and to set up XMLTV properly. It should be called things like:

"Cable" - the cable connection on your tuner card

"Composite" - the composite connector on your tuner card

Input Connections links these "friendly" names to actual physical
connections on the video card.

/dev/video (Composite 0) -> Composite

.

.

/dev/video (Tuner 0) -> Cable

.

.

You probably have all the physical inputs on this page pointing to the same
Video Source. That's what I did initially, as I thought a Video Source was
the tuner card itself, not the specific connections ON the video card.

Myth just takes the first name it finds in Input connections that matches
whatever source you want to record from (i.e. Cable) and starts recording.
If all inputs are linked to "Cable" then in my case, it would start
recording from Composite 0 until I fixed the links.

Hopefully that makes sense.

Composite 4 is input #5 in the driver. test_ioctl -p 4 would switch to Tuner
0.
