The disk activity is Myth scraping the programme listing information
from the channel the tuner is, err, tuned to, and saving it to the SQL
It's very clever, but a horrifically intensive process, that takes a lot
of time and effort on the CPU's part. I tried it and went back to using
the Radio Times website via the XMLTV scraper.
The backend should always be running to schedule the recordings,
organise the database, etc. (unless you get clever and do automated
Unless there is feed of listing information, which in the UK is either
from the Freeview EIT feed or from the R.T. via XMLTV, you won't have
any data and Myth won't know when to record shows.
Don't worry too much about errors in the logs (mine are full of stuff
Myth is complaining about but it still runs pretty smoothly) as long as
there is a few days worth of program listings it'll be fine.
