HELP HELP!!! Premiere see's 24P footage as interlaced, need render in 2 hours!

Edit: I was able to import the project into after effects, and render from there, but I'm still interested in finding out what happened, so if you know, please answer below. Thanks!

OK, normally I don't freak out about stuff, but this is one of those times where you put so much effort into finishing something, and at the last minute you get thrown a curve ball, and arg!!!!

I shot some footage for the Philip Bloom Kessler Crane competition on my hfs100 in 24P (which is wrapped in a 60i wrapper). I took the footage into my computer running XP, and used cineform neoscene to create editable files that were 24P. I didn't have neoscene on my win7 computer, but was going to do the edit there, so I loaded the trial version of cineform to get the codecs, and started editing.

I noticed something weird in premiere: When I am paused on the timeline, the video has white horizontal lines every other line, which I thought was some sort of interlacing problem, which was weird, because this is a 24p video in a 24p project. When I play the video in premiere, the white lines go away and it looks fine. When I exported out a final edit, the white lines are there (even though you don't see them when playing in premiere).

Now, in trying to fix the problem, I finally decided that I had enough time to just recopy the footage and try just using the AVCHD files, but now, for some reason, my SDHC card is corrupted and the original files are lost.

SOOOOOOO, can someone suggest to me what to do to try to get the white lines to go away from my project in premiere? I just don't know this stuff well enough to figure it out, and the contest ends today at 5PM (2 hours from now). I'll take any suggestions!

I'm pretty sure NLE's work in a 60i timeline and create interlaced frames but then delete them when it exports to 24p. So 24p going in is still 24p going out. I'm not 100% positive, but I think that's how it works. My only real evidence is that if you set your IN and OUT points in your timeline in the exact same place and export a still image, it will be one interlace field and not a whole frame.

I shot some amount of footage at Burning Man with my GH-1 this year, and have noticed that Premiere CS5 1) plays the AVCHD 24p material much better than CS4, 2) the render for 'preview' times are horrendous, (at least I think so...) 3) and upon rendering out for export... again rather lengthy render times.

This is opposed to how I use to work with AVCHD using Final Cut Express as my transcoder from AVCHD to AIC, then used JES Deinterlacer, back to AIC. Then into Premiere...

Once that process had been done, the playback and export times seemed 'reasonable'. The transcode/deinterlace did take some amount of time... but it was a 'once' per import... and not every time I diddle with the timeline, and produce a 'red' bar indicating 'needs rendering'...

I may have time a week from now to go through this comparison more carefully, and verify my claims here... but at the moment that's my subjective evaluation...
