Video rate changes at spanned clip boundary in FCP

I'm seeing a pretty bizarre occurrence on just a few clips (out of 1600+) on this project I am assisting on. I'm working with FCP 5.1.4, OSX 10.4.10.

The simplest way to describe the problem is that for a clip that is spanned across 2 P2 cards, at the boundary between the two spanned "pieces" the video rate instantaneously jumps (the video looks like fast motion) yet the audio plays at the correct rate. And the clip imports incorrectly with the duration of the clip being the duration of just the first piece + the duration of the second piece if played at say 3x normal. In the FCP P2 Import window, the duration of the clip is correct. After import in the FCP browser, the duration is wrong.

In the FCP Import window, each piece is listed as "Incomplete" when only one of the two P2 volumes it spans is mounted. Oddly, the media map indicator shows the clip as full.
When both volumes are mounted, they show as "Spanned", with the media map indicator as full.

Simple (sadly lengthy) example:
First piece of the split clip is 1:00.00, second piece is 2:00.00.
In the import window when I mount the volumes containing both pieces the duration correctly shows as 3 minutes.
Yet when I import that clip FCP lists its duration in the browser as 1:20.00.
When played, the clip hits the 1:00.0 minute mark and the video rate speeds up enough to get the remaining 2 minutes played in the next 20 seconds. The audio correct plays all the audio at the correct rate for the first piece of the clip.

So my question is: WTF? :(

Anyone seen this?

My fix is that I have to treat each "piece" as its own clip, but that doesn't feel right. Plus, I am 99% sure that ALL clips that span 2 P2 cards do NOT show this behavior.

The shooters swear they did nothing to cause this. There may be something I am doing wrong on ingest, but if there is I obviously do not see it.

Thanks in advance....

ps - yea, I know, stop trying to use FCP to log P2! :) But the client cannot afford to even buy P2Log so that is not an option...
