Clip browser won't recognise clips

I did some filming today and recorded the whole day onto my PHU-60, it was only after I had copied the data off onto my Mac that I remembered the first 2 clips were on the 8gb SxS, so I copied them across too.

As there were only two clips in the CLPR folder from the SxS, I copied those folders into the CLPR folder from the PHU. It was only when I ran everything through XDCAM Transfer that I realised the two clips from the SxS were not being recognised and were being totally ignored. I have since formatted both the card and the HDD, so can't simply start again.

I opened the MEDIAPRO.XML file and the two clips aren't mentioned in there (as they were from a different card), I thought about modifying that, as it looks simple enough, but i have no way of working out the duration of the clip (which i'm assuming is to the frame) As i can't import the MP4 into FCP.

Does anyone have any suggestions how i can salvage these clips? Thanks
