Using a PVR-150 MCE I ran into two issues:

1) The tuner wasn't recognized.

I fixed this using a Tuner=50 option on the ivtv using debian modconf

2) On boot the ivtv would complain:

ivtv0: unable to open firmware v4l-cx2341x-enc.fw
ivtv0: did you put the firmware in the hotplug firmware directory?
ivtv0 warning: failed loading encoder firmware
ivtv0 warning: Error loading firmware -3!

However, if I did a rmod ivtv; modprobe ivtv the firmware would be loaded. I created a startup script to execute these two commands (see http://www.debian-administration.org/articles/28 for debian way to setup startup scripts) and it fixed this problem. Now that I write this, I am wondering if my fix for 1) caused the problem with 2). Is there a recommended way to add module options in KnoppMyth?

You shouldn't have to force the tuner type, it should be autodetected.

Try step 4 in the CompileIvtv directions on the wiki (http://www.knoppmythwiki.org/index.php?page=CompileIvtv). You may also want to do the step to verify that your firmware is correct.

BTW - What is the history of the box? If this is an upgrade from a previous install, especially pre-R5B7 you should also do steps 8-11as noted in the R5C7 upgrade hints posting here: http://mysettopbox.tv/phpBB2/viewtopic.php?t=10116

Forcing the tuner type seems to be a common fix e.g. http://www.mythtv.org/pipermail/mythtv-users/2006-May/136062.html
there seems to be a lot of references to the Hauppauge "Tuner of the Week" club.

This was a first install of KnoppMyth
