LASTCLIP.txt not behaing well across multiple cards.

Ok, I have a confusing problem.

I have 2 P2 cards in my HD camera. When the first fills up, it starts recording onto the second. But the problem is, the naming convention on the second card starts over at 0001xx.MXF! I could be recording clip number 0467A4, and still it will start over at 0001 when it goes to the second card. If "0467A4" is a spanned clip that starts on the first card and finishes on the second, it will finish the clip by naming it correctly, but the very next clip is still 0001xx!

I have checked the LASTCLIP.txt on the second card to make sure it's not the problem... but the document is blank when freshly formatted. This is not to say that the LASTCLIP.txt on the second card is useless. Once clips start getting recorded onto the second card, the LASTCLIP.txt fills with its usual data and functions normally, just with the wrong numbers. :/ It should continue right on with 0468xx, but it does not.

Any thoughts? I have looked online but cannot find my specific problem. Any hints, suggestioins, or links would be appreciated!
