[mythtv-users] PVR-350 and TV out

I struggled with this several times.  I could get the X gui up on the TV and
everything, except I would continually get the black screen when I was going
into live TV.

here goes a bit of a brain dump, please excuse the erratic nature of the
next few sentences.

I have learned that one must make sure that permissions are all correct on
/dev/video* and /dev/fb# (0 or 1 depending) mythtv needs to be able to read
and write these devices.

as well as the Xsession needs to be started by the mythtv (or whoever you
run myth as)  

mythbackend should be setuid mythtv so that it runs as mythtv

and in the recording profiles, set the width and height to 720x480 for the

when creating the XF86Config (or XF86Config-4 on RH) file you will need to
specify your BusID and frambuffer device.

I find that I prefer the out put of XFree86 :1 --scanpci --verbose over that
of lspci for determining the BusID of the pvr350.  This command gives you
the BusID in decimal.  Then just inseert it eactly this way into the
XF86Config file.  I put mine in as PCI:00:13:00, I prepended with PCI, while
this probably isn't totally necessary, I did it anyway.

other than that the tvout howto in the ivtv wiki, I believe that you were
pointed there already, is wuite good.

Good luck

Greeting! I'm really excited to be part of this group. Now it's my turn to
post my first question.

I got MythTV running, got the Cable signal, and can watch/pause/record live
tv without any issues...on my monitor.

Now I want it hooked up to my TV :)

Let me start with my setup:
MB: Asus P4S800-MX (Micro-ATX)
Onboard Audio: ADI AD1888 SoundMAX 6-Channel Codec
Onboard Video: SiS Real 256E Graphics
Tuner Card: Hauppauge PVR-350

OS: Redhat 9
MythTV Version: 0.13
ivtv Driver Version: 17_21288 ?

I followed the directions on pvrhw.goldfish.org for installing on Redhat 9
(had to get some info from the "Installing on Fedora" section)

I am able to load all modules correctly. And I can do #modprobe saa7127 with
"test_image=1" and I see the color bars on the screen!

I can even modprove ivtv-fb and see the TV get a cursor (but anything I type
does not show up). But if I try #dd if=/dev/video0 of=/dev/video16 bs=64k
nothing happens. I have also tried #cat test.mpg > /dev/video16 and that
doesn't do anything :(

Can anyone point me in the right direction???
