I finally had the time to debug "my" livetv problem: optimize_mythdb.pl was
the solution. You can find it in the contrib directory.
Yesterday, I replaced my backend and the live tv problems were gone. So I
redid the upgrade step by step and I found out that the mysql database was
the problem.
After an export / import, live tv was a bit faster. Running
optimize_mythdb.pl solved "everything". Starting livetv takes 5 seconds,
switching channels less then 0.5 sec.
This datbase is an upgrade from 0.19 ot 0.20. Is it possible that the upgrade
messed up something?
