Introduction
Richard created screenshots during the migration from 0.20 to 0.21 on openSUSE 10.2 and started this page. We assume these instructions will work for newer version as well.

Update
YaST Software Management can install and remove packages, it can also be used for updating them, if newer versions are available. This is generally the case when unofficial and unsupported repositories are used. Official security or bugfix updates are usually installed with YaST Online Update. The availability of a newer version of a package is indicated by blue text - right click on the package and select Update.
Screenshots from the update
mythtv:~ # /sbin/init 5
Common problems and solutions
Playback Issues
After the upgrade I found that playback was pausing every few seconds. I also found that CPU utilisation was high. I did the following, but it is still worse than with 0.20.2.
It is now possible to create profiles for your playback preferences base on content resolution and it seems that any old settings are lost. I created a profile and enabled XVMC.
I also enabled SUID for the mythfrontend binary. There is also a setting relating to this which needs to be enabled.
mythtv:~ # ls -al /usr/bin/mythfrontend -rwxr-xr-x 1 root root 1559476 Mar 13 10:08 /usr/bin/mythfrontend mythtv:~ # chmod +s /usr/bin/mythfrontend mythtv:~ # ls -al /usr/bin/mythfrontend -rwsr-sr-x 1 root root 1559476 Mar 13 10:08 /usr/bin/mythfrontend mythtv:~ #
I got good playback performance (under 10.3 with Compiz/XGL) by creating a new Playback Profile with the following attributes and putting it first in the list:
Match Criteria: > 0 0 Decoder: Standard Video Renderer: xv-blit Primary Deinterlader: Linear blend

Mythweb Not Working
When I tested Mythweb by going to my bookmarked URL (http://192.168.1.201/mythweb/) the following error was displayed in the browswer window:.
Access forbidden! You don't have permission to access the requested directory. There is either no index document or the directory is read-protected. If you think this is a server error, please contact the webmaster. Error 403 192.168.1.201 Sat Mar 15 13:43:18 2008 Apache/2.2.3 (Linux/SUSE)
I changed group owner for the mythweb files from www to users:.

This had no effect.
By going to http://192.168.1.201/mythweb/mythweb.php (specify the full path to the web page) I got the following error:
Database Setup Error The database environment variables are not correctly set in the webserver conf or .htaccess file. Please read through the comments included in the file and set up the db_* environment variables correctly. Some possible solutions are to make sure that mod_env is enabled in httpd.conf, as well as having followed the instructions in the README and INSTALL files.
My .htaccess file went missing during the update! The file was still indexed in the locate DB, but I was unable to list it.

I restored the file from my backup of my root filesystem and Mythweb now works.

User Experiences
Rhulme - Thanks, this worked for me as well. CPU idle while playing was 0% and is now 50%-60%.
Moosy - I used these instruction on the openSUSE 10.3 page for openSUSE 10.2. Have seen no CPU issues whatsoever on my openSUSE 10.2 64bit machine. Like the screenshots on this page, good job.
