Perhaps a post on the ivtv mailing list? There are a few different versions on the 250 and I don't know about the MCE version.

Post subject:  fix?
ok i contacted my retailer, he says "
there is a problem with the ivtv driver recognizing this as the wrong card.
If you look in your kernel logs you'll probably find the following line:

kernel: ivtv: Found an iTVC15 based chip

This card is the newer iTVC16 based chip. You are the 3rd customer this week with this issue, I'm in the process of documenting how to fix this (it requires a source code change), once complete I'll send it to you. I will also be sending it to the ivtv developers to try and get this fixed in the source code."

im now waiting for the documentation that hes doing, tho once i get it, how could i go about applying it to knoppmyth? or is it possible?

thanks

well if he gets it to the ivtv project and they fix it then it will be included in the next version of knoppmyth I'm sure.

ok heres the fix guide

This fix for the ivtv 0.1.9 and WinTV-PVR-250 MCE problem is a temporary fix, the developers of ivtv will be releasing a permanent fix in a week or so.

This temporary fix requires a single line change in one file. This fix has only been tested on KnoppMyth. This fix will only work on a system with 1 or more WinTV-PVR-250 MCE cards, you cannot mix different models/versions of PVR cards. The fix simply forces ivtv to the correct card type since ivtv is not recognizing the WinTV-PVR-250 MCE card correctly.


To utilize the fix please follow these instructions:


1) Shutdown the computer with the WinTV-PVR-250 MCE card in it and remove the card.

2) Reboot the computer.

3) cd into the following directory:

/usr/local/lib/ivtv/driver

4) Edit ivtv-driver.c with your favorite editor and make the following change:

On line 1959 change:

itv->card_type = ivtv_card_params[i].card_type;

to:

itv->card_type = IVTV_250_V2;

5) Save the file and exit the editor.

6) In the same directory (/usr/local/lib/ivtv/driver) run the following commands:

make
make install

7) Shutdown the computer.

8) Re-install the removed WinTV-PVR-250 MCE card.

9) Reboot the computer.

10) Configure MythTV as you normally would.

That's good news Kaziya. Thanks for the info. I feel better about buying a 250 MCE now. Much appreciated.

Has this been addressed in r4v3? Can I use my 401 with my 250 MCE now?

Post subject: 
well I don't think it's fixed in R4v3 because the fix is in the pre10 version of the drivers, and koppmyth doesn't ship with pre versions, however this would not keep you from using a pvr and a 401 in the same system. pvr uses ivtv drivers, and 401 uses bttv drivers. what this prevents you from using is one of the pvr250mce that requires the workaround and an old pvr250/350 that doesn't.

Oh! That's good to hear. When I build (this weekend) I will use both cards then. Thanks!
