500s with TiVO functions?

Is it possible to pause, rewind, start live TV with the 500s? What software would I need? Currently I've got the 500s recoding and playing back from a file server on my network. Sometimes I just want to pause and then continue with live TV rather than recording.

Thanks.

You will never get full Tivo functunallity out of a 500, infact I doubt that you will get it out of any DM STB.

I'm an ex Tivo user, what I now have is a MCE PC with 2 500Cs plugged in which works a treat. I also have a DBV-C card which for when I want it gives superb pic quality and BBC HD
