You could try getting the latest 3.x ivtv drivers, then fool around with the ivtvctl (on my Ubuntu system it is at /usr/src/ivtv-0.3.4u/utils/ivtvctl)
Relevant arguments for ivtvctl: -b, --set-vbi=<mode> sets the VBI mode. <mode> is a comma separated list of: raw: raw VBI mode teletext: sliced teletext cc: sliced closed caption wss: sliced widescreen signal vps: sliced vps -B, --get-vbi gets the VBI mode. -w, --set-vbi-passthrough=<mode> sets the VBI passthrough mode <mode> is a comma separated list of: none: no passthrough cc: closed caption wss: widescreen signal vps: vps -W, --get-vbi-passthrough gets the VBI passthrough mode -x, --set-vbi-embed=<mode> sets whether VBI data is embedded in the MPEG stream. if 1, embed VBI data in the MPEG stream, if 0, don't. -X, --get-vbi-embed gets whether VBI data is embedded in the MPEG stream. At the moment I don't know which of these options MythTV expects. I'd try this first: ivtvctl -b raw -x 1 ... then toggle CC within MythTV. I've tried every combination of these options on my PVR250 using ivtv version 0.3.4u. No joy. But rumor has it the PVR350 may work better. You can verify whether your PVR 350 is passing CC info to ivtv by tuning Myth to a channel where you know CC data is. Then exit live TV, and at a command prompt, run /usr/src/ivtv-0.3.4u/utils/vbi. After a minute or two you should see the CC text. Please let us know what you find out, including whatever version of ivtv you're running. I'm trying to build a list of what works and what doesn't so future Myth users won't share out pain! -Bryan -----Original Message----- From: Greg Chila [mailto:[EMAIL PROTECTED] Sent: Friday, May 27, 2005 8:10 AM To: mythtv-users@mythtv.org Subject: [mythtv-users] Myth, ivtv, and VBI. Is it possible? I've been a mythTV user for almost two years now, and never looked back. However, I just built a mythbox for my girlfriend. Everything is working great (audio is a little off, but otherwise OK). The problem is, she loves closed captioning. I know myth has support for CC (aka VBI), and I have the options enabled in myth's setup, but I cannot figure out how to properly configure the pvr250MCE so that CC will work. The pvr350 in my box also won't work. I've scoured the net trying to find a solution, but none is available. Can someone point me in the right direction to enable VBI? I've seen some inferences in the ivtv mailing list that embedding VBI in the mpeg stream has been possible for some time, but no details on how this is possible. Is this how myth expects the VBI, embedded in the MPEG? *Any* help at all is much appreciated. Greg Chila -- No virus found in this outgoing message. Checked by AVG Anti-Virus.
