Default Playing back wrong files?

I have seen in a few old posts that some of you have had problems with ProTools suddenly playing back misc. files instead of what the waveform is indicating. We have just encountered the same problem here. Does it have anything to do with sessions that are using large timecode numbers? The session we are running is at 10 hours. Here's what happened...

Pt24MIX w/ PT5.1 on a Beige G3 266mH running OS 8.6.

The session was running just fine until a source tape (dialog) with 10:00:00:00 time code was recorded onto one track. ProTools was locked to the incoming TC from the tape. The Track appeared to record properly (waveform was drawn correctly.). When we tried to play back the track, various files began to playback that had nothing to do with the dialog file that had just been recorded. i.e. sound effects etc... We tried moving the track to a different spot, copying the track (option click), but got the same results. We then closed Protools and ran Norton's on the Audio drive. Norton's did not find any problems other than some fragmenting.

Opened Protools again, and the problem was still there. We deleted the file and tried to record over the same spot (in destructive mode with no audio input to the recording track---just dead space). The system went, "POP!" and then recorded. When we played back the newly recorded file, it played back as, "POP!" followed by misc. audio (old sound files etc...).

We then tried allocating to a different drive (without fragmentation issues) and repeated the experiment and got the same results.

We quit Protools and ran Norton again on all of the drives including the system drive. No problems were found on the audio drives but a bunch of, "Bad modification dates" and,"Custom bit icon off but should be on" errors were found on the system drive. We let Norton's fix the problems, rebuilt the desktop and restarted the computer.

Opened the session and tried clicking (using scubber) somewhere around the 10 hour mark. Instead of placing the cursor where we clicked, it jumped to some unrelated spot in the session. (sorry, can't remember where). We tried that several times and got the same result. We then recording dead space again...this time at 01:00:00:00 code, no problems. We recorded the same dialog track this time at 01:00:00:00 TC ...no problems, it worked just fine.

Has anyone else encountered the same type of problem?

Did you read Digi's "Pro Tools 5.1 Session Start—Record Start Interval " post below? Sounds like it has your answer.
