Premiere Pro CS4 does not import EX1 files longer than 1 hour

Question

I had to record a long speech and used a Sony XDCAM HD EX1 camera with a 32 Gb and a 16 Gb SXS cards. The speaker paused after 1h 26 min. I stopped the recording and waited until the green light that allows recording the segment came on. Later I recored smaller segments.
I copied all the recorded files to the PC hard disk ( Intel Quad Core 2.4 Ghz with 3.25 GB RAM with XP Proofessional SP3).
I used Sony Clip browser to watch the clips and all of them were perfect. Then I opened premiere Pro CS4 4.21 and I wanted to import this 27 GB file. In the media browser appeared only one mp4 file. All the short ones where imported normally but the big one freezed premiere and the only way to close premiere was with the windows task manager.
I checked again in the Sony XDCAM clip browser version 2.6 and you can see it perfectly. There was a detail, though: in the lower part of the preview window I saw 6 marks. When I checked the file in the disk, I found that the 27 Gb file was separated in 7 parts. Each of them was 3.51 Gb and the last one 2.5 Gb. That means that the file was cut in pieces that were less than 4Gb supposed max file lenght.
I tried many ways to import and no result. The I used the "export " of the sony clip browser. There is one choice that is "MXF for XDCAM HD". When I chose this item another panel appeared and showed a 1440 X 180 59.94i 25Mbps choice. I took it and after some time it created the 27 Gb file that I could import it normally with 4 audio tracks. But there is a drawback a "media concept" logo appeared to remeber to "buy" the program.
Anyhow, the question is: How can I import to Premiere CS4 a MP4 file created by a Sony EX1 HD camera whose lenght is more that 1 hour long ?
Thanks

Answer 1

I think  is the contrary because the clip browser copies all the foleders needed. I got this opinion from another forum that copies into Final Cut:
"My workflow is to create a hard drive folder for the project, then use Clip Browser to import the clips from the card. I review the clips, labelling them, adding logging notes, setting the status and putting in essence marks as needed (the number of characters available for the essence mark description is fairly limited). I then open FCP, create and save a new project then call up XDCAM Transfer. I select the project folder and it will pull in all the clips. I then filter for OK status, occasionally create subclips then import. The clips come over to the bin, with their names and with the essence marks converted to markers. Obviously there are backups taken - I've not mentioned them."
