[Kevin Matluk] “Well I’ll have to do with 5”
Then you’ll have to do with dropped frames as well. If you’ve already followed Chris’ suggestions then I can almost guarantee that’s what’s causing it. You can’t give one processor 6 gigs and another 4 gigs. Doing stuff like that can screw up your entire system timing which will give you many problems including dropped frame errors. Whoever put your Mac Pro together didn’t know what they were doing. Try taking one out. Even then it’s not ideal since you’re supposed to have 3 modules for each processor if it’s the brand new Nehalem Mac Pro.

Your unusual RAM configuration could be a problem. You should have 3 modules or 6. Not 5.

[Dennis Couzin] “Sean, am I misreading the Samsung HD103UJ spec : “Data Transfer Rate / Media to/from Buffer(Max.) 175 MB/sec”?”
They’re lying. Google the benchmarks or test yourself with AJA System Test. That’s your problem. You can’t run Uncompressed HD on any single hard disk without it choking. Common knowledge. The absolute fastest models (like yours) barely crack 100MB/s when empty. And as they fill up they slow down a lot. It’s odd you posted all your specs except the disk (which is the problem). Your Mac Pro isn’t “weak.” I’ve run uncompressed HD on a <1ghz G4. The difference is that it had a fast SCSI RAID.
[Dennis Couzin] “I don’t think bubble memory has as fast read/write as good hard disk drives.”
Again, Google is your friend. Some new SSDs are faster than 300MB/s. So fast SATA can’t keep up so they make ones built into PCIe cards.

[Dennis Couzin] “It’s spec’d at 175 MB/sec”
Not possible. Most Solid State Drives aren’t even that fast.

If you’re not laying back to tape then “dropped frame” errors don’t matter.

The ATI is drastically more powerful.

[Neil Sadwelkar] ”
In any case CinemaTools converts from 24 to 23.98 without any problems.”My sentiment exactly.

Change your audio speed to make it fit the duration. Then it will be back in sync.

[Ben Holmes] “Lossy video compression?”
ProRes is lossy.
