I don't know about Virgin but i have Sky and i'm guessing it's similar. It will only record the episode of it's on at the same time as far as i know, it won't get the repeats or whatever on an afternoon, though say you wanted to series link eastenders which can be on at 7.30 or 8 then it will still work, but it wouldn't get the sunday omnibus. You only see 8 days worth but by the end of the week the next 8 days will already be up so it will still keep linking them.

I'm probably wrong of course, cos i don't even have Virgin telly
