[mythtv-users] Still trying to fine tune my PVR350 TV-Out (long)

Thu Feb 5 14:27:41 EST 2004

Sorry for bringing this up again, but my PVR350 TV-Out is still wierd. When it first starts up the TV looks like it lost sync and the menu is "running through".
The X log reports the following:

(II) FBDEV: driver for framebuffer: fbdev, afb

During boot up the message log shows this:

Feb  5 18:28:01 mythbox kernel: ivtv-fb: Framebuffer module loaded (attached to ivtv card id 0)

When X starts up the message log moans about the video mode change:

Feb  5 18:28:09 mythbox kernel: ivtvfb does not support changing the video mode
Feb  5 18:28:09 mythbox kernel: ivtv: ivtv-api.c: unknown ioctl 0x803c7601

Once I start watching Live TV or a recording the picture changes to be absoultely great and in the message log you see:

Feb  5 18:31:21 mythbox kernel: saa7115[0]: decoder set size
Feb  5 18:31:21 mythbox kernel: Setting full PAL width
Feb  5 18:31:21 mythbox kernel: Setting full PAL height
Feb  5 18:31:22 mythbox kernel: spurious 8259A interrupt: IRQ7.

The relevant part of my module conf is:

alias char-major-81 videodev
alias char-major-81-0 ivtv
options ivtv ivtv_debug=1 mpg_buffers=90 ivtv_pal=1 tuner=1
options ivtv dec_yuv_buffers=20
options saa7127 enable_output=1 output_select=1 pal=1
options tuner pal=1 type=1 # PAL tuner
options msp3400 once=1 simple=1
add below ivtv msp3400 saa7115 saa7127 tuner
add above ivtv ivtv-fb
add above ivtv lirc_dev lirc_i2c
post-install ivtv /usr/lib/ivtv/test_ioctl -d /dev/video0 -u 0xff -p 0

And the relevant part of my X conf is:

        EndSubSection
EndSection

Section "DRI"
        Group        0
        Mode         0666
EndSection

I really have no idea where to start. Any pointers would help. Let me know if there is any additional information I should post.

Cheers,
Marc
