[mythtv] [PATCH] Import Recordings

[Chris Pinkham]

Couple ideas to maybe make this better:

* make it an setting option to scan for new files.
* for mpeg2 files, fire off a commercial flagger to get the seektable into
	the database.
* maybe good to just fire off commercial flagging always if the user has
	"Automatic commercial flagging" turned on.  You could fire this off as
	a thread same as above.
* maybe this could be integrated with the manual recording screen if
	there was a way/button to manually scan for new files you could use
	the entry box idea from the manual recording screen to fill in info
	about new files.

It's also been talked about about making a new packet type in the .nuv
file that would contain the program info so that you could easily move
files between myth boxes.  Your scan function could then just read the
new packet to get the info.  You might look into this as well if you're
up to it. :)
