Subject: RE: [mythtv-users] Not sure what else to try


Ok I have some more info.

- First of all I tried using /dev/v4l/video0 and that did not fix it. I
am using udev and I have double Checked that at startup it creates
/dev/video0 /dev/video24 /dev/video32. Does anybody know why it Chooses
those numbers?
- As far as kernel I am using 2.6.11 from gentoo.
- As far as ivtv versions I tried both the 0.3 branch and the 0.2
stable. The behavior is the same.

As far as firmeare my kernel does have something to say about the one I
am using:
> ivtv: Encoder revision: 0x02050032
> ivtv: Encoder Firmware may be buggy, use version 0x02040011

Can somebody tell me how to fix this? I got the rom file from the .inf
driver but where Do I place it, is it /lib/firmware or /lib/modules?

Now I followed Leigh's tips and ran the mythback and front ends on the
console and captured Both stdout and stderr. Here they are. If this
sheds some light, please guide me to What I should be doing to fix it.
Thanks again...

A couple of this I noticed is that sometimes /dev/dsp is locked and I
assume it is because of Arts. When I kill it, mythtv seems to be able to
access it. I know how to make this permanent So no problem here.

The other thing it was complaining about was that it did not like RTJpeg
(or something) under The recording profiles. I changed that to MPEG4. Is
there anything else I need to do?

I think that TVTime / xawtv don't work with the output from a
PVR250/350..
I've got a 350 at home in my myth box and can't use TVTime or xawtv. I'm
sure I've read somewhere the reason why, I think it's to do with the
output format(but I've not got the specifics to hand).
If you can capture OK using the 'cat' method (or you can do  'dd
if=/dev/video0 of=/somefilenamehere'  then the PVR-250 is working OK.

What errors do you get from mythtv?

Try running mythbackend and mythfrontend in seperate shell windows
initially so you can see any output from them while you try viewing
things.
When I first setup it was a great help when I couldn't change channels,
as I could see the response to each action I tried.

hope this helps.
