Post subject:  Tv-out PVR-350 ivtv: Write on read-only interface

Hi All.

Installed R4V4 on SN41G2 with a PVR-350 card after having R4V1 running succesfully previously - Why you ask? Don't know I answer. :) I chose not to upgrade because I thought it would be cleaner and I would configure as I did with V1.

I have everything working except Tv-out. I can record TV, I can play an mpeg with "mplayer -vo fbdev" but I get a blank TV screen when attempting to watch live TV or a recording. "mythtv kernel: ivtv: Write on read-only interface" appears in /var/log/messages at the time of the attempt.

I have changed the permissions on /dev/fb* and /dev/video* in the desperate hope that that might be the problem with no change.

Where should I look next?

My ivtv module conf is:
alias char-major-61 lirc_i2c
alias char-major-81 videodev
alias /dev/v4l ivtv
options ivtv ivtv_debug=1 ivtv_pal=1 tuner=28
options tuner pal=1
options saa7127 enable_output=1 output_select=1 pal=1
options msp3400 once=1 simple=1
add below ivtv msp3400 saa7115 saa7127 tuner
add above ivtv lirc_dev lirc_i2c ivtv-fb

My devices are:
crwxrwxrwx 1 root tty 29, 0 Apr 15 2001 /dev/fb0
crwxrwxrwx 1 root video 81, 0 Aug 23 2003 /dev/video0

Thanks

Rick. :shock:

TV out on the 350 isn't a KnoppMyth instalation issue.
