De-interlacing? Final Cut Express? iMovie? Canon HV-10

Actually you'd have to use DVCPRO-HD. DVCPRO NTSC is a standard resolution codec, and only supports 720x480. DVCPRO is a better choice, but there will still be some resolution loss depending on the source material. If the camera shot in true 1920x1080, or even 1440x1080 you will lose some resolution as the DVCPROHD codec resamples the image to 1280x1080 for 60i and 1440x1080 for 50i.

Quicktime Pro does support ProRes422, but only after you've installed FCS2 or FCP6. It's not a consumer level codec, and isn't included with the Quicktime download.

Actually both of the formats you mention are compressed formats. They are both intraframe compression types (i-frame), so each frame is compressed, but there is no GOP structure that introduces interframe compression (b-frame and p-frame), so each frame is descrete, and not dependent of other frames. Both HDV and H.264 use this GOP interframe compression.

Well, I know all of this, but like I stated before, I was simply trying to explain it so that he and everyone else could understand it. Regardless, he's going to lose quality with any kind exporting that requires compression.
