Recently my wintv duel USB tuner has started behaving strange. *It has been working perfectly on my laptop with windows 7 media center.

Schedule recordings only record for 1-10mins before the tuner fails.*
Live tv fails, after 10-20 mins the tuner "ejects"(windows makes the USB eject noise) and the tuner fails.(no tuner available to satisfy request). *The tuner sometimes "reconnects" after a few minuets or after a restart.

I am at a loss and am starting to think its a hardware fault.*

Help!
