[mythtv-users] mythtv changing video resolution when capturing to 480x480

[ryanlists79 at gmail.com]

For some reason mythtv is forcing ivtv to change the resolution fomr 
what ever i set it to to 480x480 when ever I watch live tv, or record a 
show.  While I'm watching, it won't chage when I do a v4l2-ctl call, but 
it will once I stop: 

<not watching live tv or recording>
[root at dvr ~]# v4l2-ctl -v width=720,height=480 --verbose
VIDIOC_QUERYCAP: ok
ioctl: VIDIOC_S_FMT
[root at dvr ~]# v4l2-ctl -V --verbose
VIDIOC_QUERYCAP: ok
VIDIOC_G_FMT: ok
Format:
        Type          : Video Capture
        Width/Height  : 720/480
        Pixel Format  : MPEG
        Field         : Interlaced
        Bytes per Line: 0
        Size Image    : 131072
        Colorspace    : Broadcast NTSC/PAL (SMPTE170M/ITU601)

is mythtv normally changing the resolution?

Here's the current itvt stuff installed:

ivtv_xdriver-0.10.7-8_r3843.fc6.at
ivtv-kmdl-2.6.19-1.2895.fc6-0.10.0-125.fc6.at
ivtv-0.10.0-125.fc6.at
perl-Video-ivtv-0.13-8.fc6.at
ivtv-firmware-1.8a-13.at

Kernel version 2.6.19-1.2895.fc6
Hauppauge 350 (using output as well)
Athlon 2800+

Thanks,
