If that's all that you are after the TM2T is a great box & does all these functions perfectly.
To watch live tv/record/playback, I can't fault it & would recommend it.
However, if you want to use the new ondemand players or are planning on watching avi/mkv/mp4 and so on file formats, I'd avoid it for now.
TM are aware of the issues & apparently working on new drivers, so hopefully this wont be an issue soon.
Saying that, your current SKY box doesn't support these features either, so as a replacement box, it's a good one.
