So I am trying to setup a standard sky box with mythtv. I would like to point out at this stage I believe this is legal, someone please tell me if this is not correct. Also I have reasons for doing this instead of getting MySky, I have had MySky, it is great but I prefer the features of mythtv and having a single system.

So what I what I would like is to scrape the Sky EPG off the satellite feed and put into myth, unless there is now a reliable internet based source. From my experience these tend to get taken down after a while.
So is there a good Ubuntu program for doing this? Mediaportal can do this natively but I am not aware of mythtv doing the same.
