I used to be able to use my Sorensen Squeeze with my Avid no problem...but on my new computer it just plain won't work (I get an error message about "invalid progressive" or something when I try to squeeze the QT Reference file in Sorensen). Maybe because I'm tyring to edit in a 24P timeline for the first time. Anyway I would like to try out another program for converting QT Reference files to MPEG-2 files. Any suggestions? (Other than TMPGEnc, which is a program that baffles me.) Thank you for any advice!
converting QT ref to MPEG-2

Yep. ProCoder is another one, but I've never used it.
I use Sorenson with QT 7 and have not had a problem.
Something else you could try would be exporting the video from Avid as a QT Movie using the "Same as Source" option. Not as fast as a Reference, but not as slow as a QT encode either. That might help.

Any chance this problem is arising because I'm editing on a 24P timeline (in Avid Xpress 5.0)? I'm seriously wishing I'd just captured and edited on a regular NTSC timeline, as the 24P timeline workflow seems to be rife with complications. But, hey, I'm always trying to get the "best quality picture" I can.
Hm...I started off in one Avid application...and am now editing in another. Krestofre, can you tell me where I look to see which mode it was captured in? 23.976 or 24? I am pretty sure I selected 23.976 when I first captured. But I don't know where that information would be stored.
Well, that Cinemcraft Encoder Basic certainly did a quick and easy MPEG2 conversion from the reference file. No error whatsoever. And so I think it really is a glitch between the Sorensen and the new Quicktime release. I've seen similar postings to mine in the Avid and Sorensen forums.

Cool. Glad CCE worked for you. Just because I've never had a problem with Sorenson doesn't mean a problem doesn't exist. 
For future reference, you can check the project setting by clicking one of the tabs in the Settings Windows. I think there's one that says Format, but I'm not at my Avid right now so that might not be 100% right.

Yes, thank you again. There's one in Settings called "Film and 24P", within which there's a setting called "Edit Playrate" (I'm on 23.976) and another for video pulldown (I'm on 2:3:3:2 for my 24P Advanced footage). Perhaps you can enlighten me a bit on how the playrate setting 23.976 vs. the playrate setting of 24P (which is also an option in my Avid Xpress) differs. Should I switch it over to 24P? Or perhaps it's too late, because I'm all captured and edited now. I did find when I tried to burn a DVD with a new program (from the CineCraft MPEG2) I got an error in the DVD burnder that says: 23.976 frame rate not supported in NTSC. But maybe 24P is? Just a very complicated arena.
(Gosh, just realizing -- is it possible that maybe I cannot burn a "true" progressive DVD because my capture cadence was set to pulldown 2:3:3:2 rather than just being "none"?--so maybe I did not preserve the 23.976 frame rate I shot in. I don't think this is the case, because but I understand the 23.976 framerate was always converted to NTSC 29.976 by my DVX100A. I shot in 24PAdvanced and edited on the 23.976 timeline because I'd read that this was a good way to preserve the best quality for an ultimate film blow-up or for burning a 24P DVD.)
(And it looks like others in various forums are posting problems about getting the same error message I did --something about invalid progressive sequence--when they're using Sorensen Squeeze, which makes think it's pretty much for sure a Quicktime 7.0.4 glitch.)

We're staring to mix a lot of different things here, so I'll try to sort it out.
That's not what I was talking about to determine project type. The tab you need to select to check your project is the "Format" tab. It will show you what project type you selected. The Film and 24p settings affect pulldown, and 35mm film tracking. Different things.
23.976 is the original 24p footage shot by the DVX. the 24p project type in Avid is another option for working with footage transfered from 35mm film. The difference in using 23.976 and 24 is mostly related to how your audio was captured and synced with the digital footage that you're working with. Since you're using the DVX and not telecine film transfers, you will always be in 23.976 to work with your footage.
This is because pulldown needed to be reinserted into your MPEG-2. I'm not that familiar with CCE, but it sounds like you didn't author your MPEG-2 file correctly for a progressive DVD. See if you can find something about Pulldown in your settings for CCE. The MPEG-2 has to have that flag for some authoring programs to accept the file.
I'm a little confused here. Are you referring to the cadence setting in Avid, or in CCE? If you're referring to Avid, then no, that's not possible. You cadence has to be set to either Advanced or Normal pulldown (depending on if you shot Advanced or Normal on the DVX) in order to capture 24p footage into Avid. Setting it incorrectly, or setting it to none, and capturing in Avid will result in choppy footage and your next post would be "Why is my footage so choppy?"
That is correct.

Then I guess I set it right. Capture cadence was set to Advanced 2:3:3:2, and since I shot in 24P Advanced mode, this would be the correct setting.
How can I repay you, dude? Can I give you advice? Like on color combining your shirts and ties? You look like a winter in your photo. In the meantime, THANK YOU!!
