I've not seen a blue screen, but if you've got X running okay through the PVR350, then the ivtv-fb module is loading. If you run 'rmmod ivtv-fb;modprobe ivtv-fb osd_compat=1;dmesg'. The last lines from dmesg will contain the ivtv-fb module output, which should be similar to the following: ivtv0-fb: Framebuffer at 0xd1510000, mapped to 0xe2090000, size 1665k ivtv0-fb: === Validated display mode === ivtv0-fb: Display size 720x576 (720x576 Virtual) @ 32bpp ivtv0-fb: Display position 1,1 ivtv0-fb: Display filter : on ivtv0-fb: Color space : RGB ivtv0-fb: === Display mode change === ivtv0-fb: Display size 720x576 (720x576 Virtual) @ 32bpp ivtv0-fb: Display position 1,1 ivtv0-fb: Display filter : on ivtv0-fb: Color space : RGB ivtv0-fb: Running in compatibility mode. Display resize & mode change disabled ivtv0-fb: Framebuffer registered on ivtv card id 0 Without the osd_compat option (compatibility mode), MythTV can't properly control the PVR350 framebuffer. It still runs & can use the mpeg decoder, but it won't switch off the framebuffer or show the osd. This will result in a black screen with sound when trying to watch something. To see if you're getting anything out of MythTV, you could first run 'ivtvfbctl -v 140' (you may need the '-d' option to specify the correct framebuffer device). This will make the framebuffer semi transparent. Any video MythTV then plays back will be visible through the desktop, albeit a bit dark. -- Ian _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
