#The PAR: Very Unreliable

I have been using the 1.30b very hard, around the clock, for the past three weeks doing all these video rotoscope effects. Extensive use of the DPS_PAR.PXP as well and outside of a few known bugs in file management the version works without fail. I have a thought that your problems seem to be intermittant file corruption. ie. it seems by your description that it is never a repeatable problem. Assuming that both the drive and the board are functioning OK you might look else where for the problem. Like cables and power supply intermittancy. I once had a problem with one of my machines corrupting a frame during the rendering process. I finally discovered that with all the cards and RAM I had installed my power supply connectors were getting very hot and burning the plastic near the +5 volt pins. The current was a surprising 16 amps at 5 volts. Well this was only 80 watts but the problem was the 16 amps flowing through the tiny pins of the power supply connector to the MB. This connection, over time had over heated to the point that it had reduced the springiness to the pins and the connection had become intermittant. I ended up soldering the +5 volt wires into the MB and my files were clean 100% during the rendering. The point of all this is that with all the junk we add to these MB's the power supply connections are for the most part inadequate and need beefing up to support the added current loads. Did you ever feel the PAR, the Targa+ and the TBC IV? They all run very hot. This heat is indicative of high current through that little connector.
