25p in 50i stream, pFrame split across 2 iFrames

I have captured stream from satellite broadcast. The material is progressive, encoded in interlaced stream, however the progressive frame is not split to two fields in one interlaced frame, but across frame boudary. To illustrate the situation, normally P1 would be split to frame 1 field a and b - F1a and F1b, but in my case it is like this: P1 is split to F1b and F2a, then P2 to F2b and F3a and so on.

Do you know method how to recreate correct progressive material from this? (preferably in Vegas)

This might work.
Turn Off Quantize to Frames and trim half a frame from the start of the video.

If that doesn't workthen try this. Change your project to 50p. Field Order None, default Render Quality Best Trim off the first frame (which is actually a field). Nest that project back into a 50i Project. Render that out. You should now have a correct 25PsF video.

Thanks. The second method seems to be working.
