[Bob Cole] "1. Why should I even consider a 3rd party app for the transcode? "

It's just an idea. Something like Episode would most likely do the job and is easy to set up with a custom preset e.g. more automated. With Episode you can create a watch folder, then whatever you drop into that folder will automatically be transcoded to the customized preset. But Episode costs money and you already have Compressor.

[Bob Cole] "2. What do you think of my new approach of just biting the bullet from the beginning and transcoding everything to ProRes? "

If your workstation is having trouble displaying and editing multiple tracks of Long GOP MPEG2 then you need more processing power. Editing XDCAM EX natively is very processor-intensive but easy on the data Transfer rates between the computer and the separate drive where the actual media resides. That's why firewire drives are okay to use for this scenario.

Conversely, Pro Res doesn't need nearly the same processing power but you do need higher transfer rates between hard drive and computer. Editing multiple streams of Pro Res probably requires an eSATA connection.

The solution for you at this time is to convert your EX footage to something that's easier for your processors to handle. That's what Pro Res is for. A lightweight but high quality "I" frame codec.

[Bob Cole] "3. Given that I will have to move from FCP7 to something else, most likely Premiere Pro or Avid, how would their handling of the XDCAM files influence your choice?"

Both PP and Avid MC handle native EXCAM EX just fine. When choosing a successor to FCP 7 how they handle XDCAM files will be the least of your worries. Remember that even with another NLE there's still going to be the basic issue of processing power vs. Long GOP.
