One thing, the "Writing PAT & PMT" message should not be VB_IMPORTANT
I have it at VB_RECORD in my local tree.

As well as that, I've found another cause of some zero byte records.
Sometimes it ends up tuned to the wrong transport and so it
can't find the PMT it's looking for in the PAT.

since this has only happened to me since I've added the bbc hd
test mux, I'm going to have a careful look at the mux frequencies
and how close they are. see if I can work out why.

(and it seems to always end up on the new mux...)

This is where it should be. The scanner should control the cards
to retrieve the info for it, and then it can do the processing.

This allows us to have a place to implement more intelligent
scanning methods.
