FCP only utilizing .02 CPU on Render?

Question

Since yesterday my FCP and Compressor have been going haywire. Originally my problems started when i was using compressor to render out a single pass.m2v and a 48:16 aiff, for a dvd to send out to my client. I have been doing this conversion for the past 6 months it takes no longer than an hour and some change. Well Thursday comes and i get the unknown time issue. At the same time though my FCP render time has quadrupled. Im using a 1st Rev MBP 2.16 15" with 2gb ram, connect via GigabitEthernet to a G5 i use as a server for my raid array. My raid is connected to the G5 via multilane to a PCI-E HighpointTech card. The footage i am working with is DV, and titles that have been converted to anamorphic .mov a show only takes about 20 min to render normally, however since thursday my computer is now taking 3-4 hours to complete a render, and during which is only utilizing .02 of the CPU. I am stumpped i have trashed the render files, trashed the preferences, and zapped the pram. I searched the forums but i couldnt find anyone with a similar problem, i am seriously about to just wipe my computer and fresh install everything

Answer 1

Im running 6.0.4 on osx 10.5.4, Thats what i originally thought the issue was, so i migrated all the media files over to my internal HD, and i still got the same results. After that i thought it was maybe something got tweaked in the sequence so i migrated a previous project over to my computer that had rendered out normally 3 days before, and to no avail it took 3 hours and 20 min. So at this point im thinking either there is an issue with my hardware, or gremlins are messing with me, because i cant think of a single thing. I really dont want to have to wipe and reinstall, that would set me back a full day, and right now my workload just wont permit that.
