After giving up on xvmc on a prior Ubuntu Breezy Mythtv install, I recently installed Knoppmyth. Analog cable has not worked with either distro. I've tried all settings (bcast, cable, IRC HRC, etc. The picture freezes after a few frames with bands of noise at the top and bottom of the screen. The noise continues to be recorded and displayed by Myth, when Myth doesn't crash, that is. I think the IRC setting was the best. The picture was in color. The other settings resulted in a frozen b/w picture.

I searched the web and all the info I saw seems to imply analog should work with this card, but I couldn't find definitive testimony. QAM works great!

The card works okay in this system with the Windows Fusion software.

Thanks!

Well...I've answered my own question--at least partially. Fusion 5 Lite analog does work perfectly with TVTime under FC5. Ditto for QAM using azap and mplayer. I have not setup and run Mythtv under FC5 yet, though I did manage to install it.

I'm sure there's a way to get Fusion 5 Lite analog working under Knoppmyth too but, motivated by the recent support for this analog tuner, I compiled and installed from V4L mercurial source under Knoppmyth. This resulted in nearly immediate kernel panics on boot. Knoppmyth is great when everything works, but it's risky to add or change anything! Broken packages made the mythtv-suite install under FC5 quite challenging too and I still have to complete the setup.

Details such as kernel version, bttv module, etc. as you may find this working in a future release...

When the source is open, the possibilities are endless!

I've setup Mythtv on three systems now--Ubuntu Breezy (2.6.16), Knoppmyth (R5C7) and Fedora Core 5 (2.6.16)--all with the same problem. I've only recently discovered the problem is with Mythtv, rather than the V4l drivers, because the TVTime ap in the FC5 distro tunes the cable analog channels and renders video from my Dvico Fusion 5 Lite quite well. I'll try to move the box to a location with OTA reception and try NTSC with an antenna.

QAM cable has not been a problem but Mythtv locks to a green screen or fozen picture immediately after displaying a few frames of a newly tuned analog channel.

I overwrote my Ubuntu and Knoppmyth installs. Here's the FC5 info. Perhaps I'll look through the mythtv users archives again.

Thanks,

The 4th post down here:

http://www.gossamer-threads.com/lists/m ... on;#170986

indicates that mythtv cannot support both analog and digital sources from the same Fusion Lite card.

While I understand that simultaneous usage would cause problem, I don't understand how tuning one or the other should cause problems. The Dvico Fusion Player Windows ap can do it so there's certainly no hardware limitation at play.

Furthermore, I think I did a V4l only setup once and had no luck. Don't remember for sure--I've tried so many things. Guess I could backup mythconverg and try removing the DVB tuner in mythtv-setup. I sure don't want to hand enter all my zap2it >> QAM mappings again! Will the mappings in my QAM video source remain, if I remove the DVB tuner and leave only the V4l tuner remaining? It's very easy to add the tuner back in--not so easy to add the QAM source with about 20 customer channel mappings!
