i tried the usb and it seemed OK, but then again my hdd seemed to wake each and every time when I was testing cross epg to download automatically, the problem only seemed to occur at the time when I have the epg set to download but a couple of times seemed to work ok so don't know if it was just having a good day with the morning download on the usb, I packaged the box up with my hdd and sent back to WOS yesterday so hopefully I should have a positive update soon when it returns.
