Well, Mine has the occasional problem like the fast forward rewind bug and it sometimes freezes if I have too much on the hard disk but all in all it's been great especially with the series links as BBC iPlayer was on the blink until my VM box got a software update the other day and whilst i'm saying that a little off topic, difference i have noticed:
1) On startup the display on the box has things like PL:13
2) Iplayer works
3) You only get the VM logo and not 'powering up, just a moment'
Well back to the Top Up box, seems to be fine for me so it is not abnormal for it to work well Jefferson T lol.

PS- I ended up cancelling anytime after the first £5 was taken cause it was rather awful and took off personal disk space
