Advertisements Well I'm coming to the conclusion that my HD103UI drive must be defective. Got to watch a bunch of playback degradation tonight, even without it being busy doing anything else. Rewind - replay, and no issue. Can't really see this as being anything other than issues with the disk (or memory I guess). Already have WD10EVCS on the way, so we'll see if it's the drive or the 'system' RSN. BTW: Buy.com have a presence on eBay which I was not aware of until yesterday. As eBay are kind enough to send coupons on a regular basis, and Buy.com no longer do ... this proved useful as the price of the EVCS was 112.50 after 10% off, with free shipping (and being Buy.com it still shipped within 12 hours even with free, budget shipping).
