48k audio errors all of a sudden

I've been using 48k audio input for years on my M100HD system, but just upgraded some things and now the recorded audio (voice overs) is overlapping and severely jumping around - obviously a data rate issue. Sure enough, when I reset the inputs to 44,1k it records fine. I was operating on Tiger, but had upgraded my QuickTime.

Now, I've upgraded my entire system to M100HD v.13 and Leopard OS.
I thought a thorough upgrade like that would likely solve my data rate problem, but it didn't -- still there.
Any ideas?? Thanks.

System: G5; 2x3 Ghz Intel; 8 GB ram; Mac OS 10.5.7; Media100 v.13.0.3; QT v. 7.6.2

Thanks, Floh,

It looks like I'm dead for recording mic audio until I get that fix from M100. I tried all my datarate settings and they ALL record bad now, not only 48k. Yikes.
Incoming audio files are OK, I just can't record (acquire) audio through the system.
I'll email Wick and see if he knows anything. Thanks.

Thanks for the responses.
Gregg, I'm just acquiring voice over tracks using analog mic inputs into the AJA box from my mixer.

Wick gave me some ideas, and I just now had a chance to go test my system again. Must be the magic in the air, because without changing anything, my test recordings are now all perfectly FINE, wouldn't you know. Tried one at 48k, and at 44.1k and both are just as smooth as baby powder.

According to Wick, it may have been an anomaly where I needed to simply open up the AJA control panel and click on some things there and then close it back up without changing anything. Sometimes that will clear the system and all is well. I did that, so perhaps that is what corrected the problem this time.

Hopefully, that took care of it all and I won't be back here beseeching you guys and gals for help again! :D
Thanks again for the insights and attention.

Ha!
I just hope this isn't what we old video/TV guys called the "Engineer Effect", where the (insert your tech problem here) goes away while the engineer looks at it and then promptly resumes once the engineer leaves the area! Anyway, now I get to trade my audio problem for a video input/output one. Can't get the system to see my Beta deck or output video to my monitor. . . sigh.
