In 0.18.x, the myth:// URLs are given if myth can't find the recording
in the same directory path on the local backend as it is on the backend
that recorded the file. In SVN, myth will also check the local
backend's RecordFilePrefix directory for the file and use a local
filename if it exists there, otherwise it falls back to the myth://

I thought we went over this. The 8 days is because in 0.18.x, errors
are kept around for 7 days and the cleanup job only runs once a day,
so the jobs could be around for almost 8 days depending on when they
ran and when the cleanup job ran in the housekeeper. In SVN, this
has been shorted from 7 to 4. I think you could still have deleted
these jobs from the mythfrontend status screen though by using the
popup menu on an errored job.

There is a volume control for ivtv compatible cards right in the
recording profile editor. This has been there since the ivtv
support was added to Myth.
