Thanks, I've investigated the problem using one of the pictures. I have used the reference jpeg decoding library and this shows no problems with the file. I have tried removing the EXIF data from the file and it then imports into lightroom with no problems, so lightroom doesn't like something in the EXIF data.

Adobe are supporting anyone testing their beta lightroom software, so I will contact them to investigate what is causing this.
