/dev/mixer is OSS

Change mixer device to "default" (no quotes) or output device to /dev/dsp

Sounds like you have corrupt seek tables (something about them changed 
between 0.21 and 0.23), so they need to be rebuilt.  Existing preview 
images (those created by 0.21-fixes) work fine, and new recording seek 
tables are good for 0.24-fixes, but when 0.24-fixes tries to create a 
large-image preview of an old recording for MythWeb, it fails.

You'll want to do http://www.mythtv.org/wiki/Repairing_the_Seektable on 
each recording...  You can do that easily enough with a script and much 
patience while it runs.
