I just installed KnoppMyth R5A16 on my box with a Diamond XtremeTV PVR 550 PCI card (MPEG hardware encoder).

The install seemed to go pretty well and I tried my best to configure myth correctly (not having done this previously).

Linux boots right to MythTV but I'm unable to view live TV. I get some wavy lines for a bit and then the screen goes mostly black. The channel lineup appears to be working correctly since I can see channel descriptions when I change the channel.

Did some searching of this forum to try and figure this out but no joy yet.

'ivtvctl -a' indicates that the driver being used is "Vanilla iTVC15 card". This doesn't seem right.

The chipset on the PCI card shows:

Conexant MPEG II A/V
CX23416-12
0428Y1CV
0429 TAIWAN

Someone else said they thought this was the same chipset used with the Hauppauge PVR-150, but I'm not sure.

What should I try next?

Thanks,

Jon

never heard of that chip which most likely means it's never been mentioned on this forum. you will need to go to google and/or the ivtv mailing list.(assuming ivtv supports that card)

It looks like this card is supported since ivtv 0.3.2i

YUAN PG600/DIAMONDMM PVR-550 (CX Falcon 2)

I downloaded the latest ivtv (version 0.3.6x) and complied it per the instructions on the knoppmyth wiki.

I copied msp3400.o to /lib/modules/2.6.11.9-chw-2/kernel/drivers/media/video

I ran mythtv-setup again but didn't see anything new.

I tried running myth again, but same deal as before.

What else do I need to do?

Jon

Found this on google:


How do I set this?

Jon

put that information in /etc/mythtv/modules/ivtv the ivtv tuner stuff may or may not already be there and may or may not be commented out you should see what I'm talking about when you edit the file.

Still not working, but when I try to watch live tv now I get what looks like an untuned channel. Tried changing channels, but they all look the same.

Should I get rid of the msp3400 stuff?

Did I copy the wrong driver over previously?

Should I run mythtv-setup again?

Here is /etc/mythtv/modules/ivtv:

don't know it's obviously very new support, you might have better luck over on the ivtv mailing list.

This is interesting...

I rebooted the computer and tired watching live tv from myth and it actually worked! I can even change channels.

However, I've got no sound and the video is super choppy.

This might have more to do with configuring Linux than anything else I suppose. I noticed that the TuxRacer game also suffers from lack of sound and choppy video also.

I'm using a fairly weak processor in this box (Duron 800) but it should be adequate as it has worked well as a PVR under Windows with both Sage and BeyondTV.

Where should I look for info on configuring sound and video?

What info do I need to retrieve for this?

well if I were you I would start another thread with details like which video card you have and which video card. quick hints if you have nvidia did you install the drivers? have you tried alsaconf?

When the source is open, the possibilities are endless!

Be aware that there are 2-3 copies of many of the ivtv-related *.o or *.ko kernel modules in the recent KnoppMyth alphas. At minimum, they're in both the ivtv and v4l2 directories.

After performing the make installs, I use updatedb (<wait for finish>) then a good ls -arlt `locate msp3400.ko`, for example to figure out where extra copies of the modules may be and replace them with the most recent one.
