Just got an amstrad PVR3 sky+ unit, what problems should I look out for?

Question

I had no choice on which unit I got.

I already no about the USB port having no power

Answer 1

main problems i noticed on mine was that sometimes it takes more space on the hard disk than required. It states 7% on the program info but took up 12 % and other things like picture sometimes goes green then back to normal. If this happens within the 1st year take out to warranty when sky contact you as the last thing you need is to be without the box if it goes faulty as it cost £100 to replace it from sky.--rip off i know.
