1) If you are upgrading from a version of KnoppMyth before R5D1, and you have a PVR card, you must drop all of your card definitions and recreate them! See steps 8-11 on the CompileIvtv page on the wiki for details. This is necessary because the version of the ivtv driver included in R5E50 uses different input names and numbering to conform to the standard V4L2 interface, and the DB configuration contains references to the obsolete names. If you do not do this, you will see all sorts of bizarre and mysterious errors.

8. Edit your /etc/mythtv/modules/ivtv file and remove the "simple=1" option for msp3400. If it has already been done, the following command is a harmless "no-op".

sed -i.orig -e '/options msp3400/s/simple=1//' /etc/mythtv/modules/ivtv


9. Edit your /etc/modules file and remove the line that says "ivtv" around line 45. If it has already been done, the following command is a harmless "no-op".

sed -i.orig -e '/ivtv/d' /etc/modules


10. Reboot the system. Do not skip this step!!!

11. After the system comes back up you will need to drop and recreate your cards definitions in mythtv-setup. See the directions for GettingBackIntoMytTVsetup for more detail. Do not skip this step!!!

* Stop the backend (as root, /etc/init.d/mythtv-backend stop)
* Run mythtv-setup
* Clear all of your capture card settings by choosing the option to "(Delete all capture cards)" under "2. Capture cards"
* Restablish them using the "(New capture card)" option under "2. Capture cards"
* Setup the correct mappings from capture card input to video source under "4. Input connections".
* Exit mythtv-setup
* Restart the backend (as root, /etc/init.d/mythtv-backend start)

Note that because of the changes in the drivers you may see a different set of input names for your cards. The changes to the names and internal numbering of the inputs on each card are why you must do this after an upgrade, so that the DB isn't pointing to the old numbers.
