You can encode a sample. You do not need to re-encode the whole project to see if it works.

Because Power Director only outputs NTSC at 29.97 fps I remuxed the Ady's original AVCHD to 25 fps in TS Muxer, which had the advantage of working with a PAL version in PD and being able to work with my PAL GOUT as it was. Then I ouputed a 37000 Kbps 1080p 25fps Mpeg2 which I reencoded with multi AVCHD still at 25fps and then changed the framerate to 23.976 while making an AVCHD in TS muxer with all the soundtracks. But I did it the exact same way with Jedi and it worked.

Will Power Director export an uncompressed/lossless AVI? If so, you could then change framerate in Avisynth before sending your video to the encoder. This would save you re-encoding twice. I know you paid for it, but it sounds like this program and this workflow is causing you problems, whether it worked once or not. I do not understand why you re-encoded (the first time) to MPEG-2.
