My votes for all three of these possible causes. 1) Power Supply (Likely older models?) - Lost my old PVRUSB2 Model #29061 because I think the power supply shorted-out, and the power strip surge protector likely could not handle this scenario. Oddly, this scenario very likely tripped two separate breakers in the house just as I heard a very loud pop noise! Not just the breaker of the house circuit the PVRUSB2 device was on, but the bedroom as well. Happened more than a year ago, and never again. Shortly there after I found the PVRUSB2 the only disfunctional device within those two circuits. (I probably should have tested the unit to see if it were still good using a known good power supply, but the cost of the power supply would have costed just as much as a new device.) 2) Poor RF Reception/Tuning - However as Mike has already speculated, I think I've also seen this reset with poor reception as well. Too much interference within the signal requiring more processing of the signal to rasterize static or poor reception. However, could be related to power supply or overheating. 3) Hardare Level Bugs - Also as already speculated, when no source of the problem can be found, it usually is found to lie within the proprietary code. Darn good devices. But it only takes one part of a device containing a million components for it to fail. Sounds like your device is a newer model. -- Roger http://rogerx.freeshell.org/ _______________________________________________ pvrusb2 mailing list [email protected] http://www.isely.net/cgi-bin/mailman/listinfo/pvrusb2
