Probably not the issue, but I have to ask: Do you have a 10-second selection area and then, in the Render As box, have you selection the “Render loop region only” item?

Maybe a Preview window setting? Is the Preview window set to Best (Full)? I Downloaded your files (thanks – made troubleshooting easy) and was unable to recreate your problem, rendered, reimported and it all looked great. Actually, I was unable to even get an image that looked like yours: Full/Auto looked fine, Half resolution looked worse. It looks suspiciously like interlacing (jaggies on the horizontal, but the vertical is clean), but I wasn’t even able to get a screenie that looked like yours by changing the project to Interlaced.

My guess is “no”, since the Windows version of QuickTime is a crippled “light” version of the real thing that lacks most of the professional codecs needed to make a Mac play nice with a PC, but I’ve never tried QT XDCAM so…
Did you try it? Did it work?!

How are you going to do the FLV conversion?
If you are doing it yourself, then a lossless intermediary to your hard disk is how you’ll want to proceed: AVI + Lagarith codec is what I’d recommend.
I suspect you mean “FLV on YouTube” et al, right? In that case, you can’t just create a humongous lossless intermediary, because you need to upload the file, so we need the most efficient, best encoding we can get. This is a longish discussion, but it starts with MP4 (H.264), I’d recommend Main Concept AVC and a data rate up in the 10-20Mbps range.

Two different questions here, first the easy one:
The CostCo machine is going to be better. Bigger screen. Faster renders. I’d bet better battery life.
The second question concerning whether it’s adequate for video? Well, yes, adequate. But, quite frankly, if you simply had $1,000 to buy a video editing machine, it is going to pale in comparison to $1,000 thrown at a desktop with a 24″ monitor. Are you really going to need to edit on the road? There are some people that do, like wedding/event producers that need to compile a quickie montage by the end of the day at the reception, but the vast majority of us end up tied to the wall (batteries) and, as you note, external drives anyhow. Laptops are just miserable to edit on, in terms of screen size, interface touchpads, performance and price, to be perfectly honest.

+4dB according to what or relative to what or measured in what? When you render the file out and compare it with the original in Premiere? I have seen oddness like this transferring from app to app (or platform to platform), but I can’t tell what’s going on here.
I suppose a manual solution is to just insert all these clips into the same track and bump the track level down -4dB? Not automatic and I’m sure you figured this out already, but it’ll work.

If it is crashing at exactly the same point, you can just create a selection area (loop region) and render out a second or two of that spot as an intermediary and insert that back into the project with frame-accurate positioning and then do a normal render. I have solved quite a few trouble spots this way, even ones that don’t have a cause I can figure out.
I’d use AVI with the Lagarith codec for this purpose.

Doesn’t look like pan/crop (the icon/button is gray) and I assume it’s for all clips in the track? Open Track Motion dialog again, right-click the area and select Restore Box. Also (and this gets me all the time!), check the Sync Cursor item (lower rightish): it’s very easy to have an earlier keyframe affect the current frame unintentionally, so look for keyframes on the Position timeline in the dialog and delete what you need to delete and/or Restore Box what you need to restore!

1 hour of video into 500MB is a data rate of about 1 Mbps, which (as has been pointed out) is very, very low and for Internet distribution only. Since you are trying to play your movies back locally and maybe burn to DVD someday, maybe consider that DVD-Video discs usually have data rates of 6-7 Mbps and you get about an hour of video onto a single-layer DVD, right? That’s a few gigs an hour.
I think I might recommend going with MainConcept’s MP4 (H.264) format at 6-7 Mbps. It’ll look better than DVD-Video and it’ll playback on your modern media player. Ideal for future editing? Nope, but it’ll work. You might even find that 2 Mbps looks OK, but 1 Mbps is reaaaaallly pushing it and I think you’ll feel that the quality is unacceptable at that rate.
The other idea that is implied in most of the posts here is that if even 4 GB per hour is too large, then you should very seriously consider getting another hard disk drive. I know $100 isn’t exactly cheap, but that’s like 250 hours of video, which is a lot of home movies!

The “x32” refers to the color depth of each pixel and not extra resolution.
8-bits per color channel: R + G + B + Alpha = 32
