1. Are you sure, it's the PVR-150's imgae and not the HVR-1600's image.
I goofed up the CX23418 A/V decoder's video scaler setting and the fix
just went to the main v4l-dvb repository around Monday or Tuesday.
In /var/log/messages you may see "cx18-0 843: invalid size" (or
something like that) if that is the case.

2. When the PVR-150 image is wrong can you do a

$ v4l2-ctl -d /dev/video0 --log-status
$ v4l2-ctl -d /dev/video1 --log-status

And post the results.

3. Also, MythTV can do Picture in picture. What do various PiP
combinations look like?

Andy

Hi Andy. Thanks for the quick response.

First, I'll let you know that I managed to switch the inputs around so
that the 150 is the default (by removing all inputs and re-adding them
in the order I wanted for watching TV - not recording). With this
configuration the HVR 1600 NTSC is the second input and the 1600 ATSC is
third.

In this config the 1600 NTSC is now the one with the too-wide display.
The 150 (the default card for TV watching) displays correctly.

I checked the logs (current and the backup) but didn't find "invalid
size" in either.

I ran these when the display was showing the too-wide format - here are
the results:

The PIP, when started while the 150 is displayed, is showing the second
card too wide too. Switching PIP just moves the too-wide display to the
other display.

This has me leaning towards a MythTV problem.

Can you kill the mythbackend and bring up two captures in two mplayer
commanlines, one on from the HVR-1600 and one from the PVR-150?

$ mplayer /dev/video0 -cache 8192
(another terminal window)
$ mplayer /dev/video1 -cache 8192


MythTV will leave your cards set at 480x480. Before starting a capture
you can use v4l2-ctl

$ v4l2-ctl -v width=720,height=480,pixelformat=MPEG
$ v4l2-ctl -V

to set the size back to the default.

Hmmm. I guess I'll need to see more extensive debug messaging turned on
for the cx18, ivtv, cx25840, and cx2341x modules to see what command
might be getting rejected and what the scalers are being set to.

Take your time. I have a cold and can't think too clearly right now.

Everything looks OK at first glance - except for the cx25840 module
reporting "system DK" seems odd. That may not matter and just may be a
"don't care" for NTSC.

Doing this I see two mplayer windows, both displayed to the correct
widths. I tried to take snapshots but only one of the windows would
capture. The other always came out black (only the snapshot, however -
the 150 window).

I did this and then double checked if MythTV was still displaying
incorrectly. It does.

BTW, the ",pixelformat=MPEG" was not recognized by the version of
v4l2-ctl I have, which is from the latest ivtv release (1.0.3) from
Linuxtv.org (http://linuxtv.org/hg/v4l-dvb/archive/tip.tar.bz2)

Me too, or rather I'm just getting over one. Nasty bug goin' 'round.

I don't know how to turn on the debug stuff, but then is it necessary if
we're confident this is MythTV and not the driver? Should I take this
over to the MythTV Dev list?

If you still need the debug output, just point me to the info. I know
it has to do with the parm option listed in the modinfo, I'm just not
sure how to set this (in modprobe.conf?)

Thanks for the help Andy.
