FCP 5 has problems with how I did projects under FCP 4.

Question

For the most part, I've been very happy with FCP 5, but it's very buggy in a couple of respects that pertain to how I create my projects. Now, I'm getting an error that is preventing me from finishing a project, so I don't have to tell you how critical my issue is, nor do I have to emphasize how quickly I need an answer.
To begin with, I will explain how I did my projects under FCP 4. I would begin by capturing all the raw footage in OfflineRT with my Power Mac G5 dual 2 GHz, then copy the project file and all media files to their respective locations on my 12-inch PowerBook G4, for portability. I would complete the offline edit on the PowerBook, then create an online project file, which I would then transfer back to the Power Mac. I would recapture footage in the new project, everything would fall into place, and all was well.
Since "upgrading" to FCP 5, this method doesn't seem to work anymore. The first sign of a problem was when I created the online project file on my first FCP 5 project. After an attempt to re-capture the footage on the Power Mac, I got an error message that the video was in an incorrect format, or something like that (unfortunately, this was some time ago, so I don't remember the exact phrasing of the error message). I was able to resolve the issue by unchecking the box in the media manager to delete unused media from duplicated items. This forced FCP to create an online file that captured every frame of my original raw footage, not just the parts that were used in the online edit. It took up more space, but at least I could get the project done.
Now, I'm getting more strange behavior, and it's preventing me from completing my latest project, even though I'm following the same steps I did on my previous project. The first thing I noticed this time was when I first tried building the online project file using Media Manager, it took a VERY long time to build the list of used media - something on the order of 15-20 minutes, when before it only took seconds for similar projects. Then, I got the following error message once the new online project had been created:
"Reconnect Media Failed: An unknown error occurred while trying to reconnect C-2 to the new offline file." This error kept occurring multiple times when I clicked continue until I finally checked the box next to it asking to ignore these reporting errors.
C-2 is one of the master clips for my project.
Undaunted, I proceeded to see if moving the new online project file to the Power Mac and re-capturing the footage in NTSC DV would work. Curiously, the Power Mac needed to capture C-2 twice. Although the length of the clip is only 45 minutes or so, FCP needed to capture 90 minutes. Unfortunately, after capturing, I got the same error message as before, but with different phrasing:
"Reconnect Media Failed - An unknown error occurred while trying to reconnect C-2 to the newly captured media. Try recapturing this clip to resolve the problem."
Recapturing the clip doesn't solve the problem. I keep getting the same errror message. Since this clip is one of my master clips, I simply cannot complete the project unless I can capture this clip somehow and have it reattach to the offline files.
The only thing I can think of, since I've been making projects this way since FCP 3 with no issues, is that it has something to do with FCP 5's new multiclip function. I have been using it extensively, and I suspect the error I received the first time was because every clip was linked to others through multiclips, and some shifting of in or out points may have occurred, which broke this link. Forcing FCP to capture all raw footage in its entirety resolved that issue the first time, but not this time.
Would someone PLEASE tell me ASAP how to fix this? How can I complete my project in online, DV-NTSC quality? Is there a possibility I can recapture the files in my offline project in DV quality, perhaps?
How can I prevent this from happening in the future? As I said, this never happened before I upgraded to FCP 5, and if this is the price I have to pay to have multiclip editing, I don't know if it's worth it. Maybe I should get a refund.

Answer 1

Finally found the answer myself. My camcorder glitched during the offline capture session, and it didn't recreate the glitch during the online capture, so the frame counts were different.
