Hi andy,
Greetings from Nepal!
Option 01

To digitize your media, your post house must have used an I/O hardware (ie, AJA, BlackMagic, Matrox, Blufish etc). These cards use their own properitory codecs. Ask your post house for vender of the that card and search the website of that card manufacturer to find the SOFTWARE only version of the codec which is also known as VFW (Video For Windows) codec which makes it possible to work with the digitized file without the presence of the actual hardware through which it was digitized in the first hand. This way you’ll avoid any re-encoding of the file. (I own Matrox cards, so when I digitize something, I provide with the Matrox VFW codec along with the digitized files to the client so the file can be played back on their machine without any Matrox card.)
Option 02 (works only if the file is playable in FCP)

Use ProRes 422 HQ. This needs re-encoding, but you get a quicktime file in decent quality indistinguishable by eyes from the original capture. Ask your editor to re-encode the files to PrpRes 422 HQ in Final Cut Pro. With the presence of Quicktime for windows ver 7.6.6 or later, Premiere CS4/CS5 can playback it in real time.
I’m a colorist and I use ProRes 422HQ everyday to render from Apple Color to master out it from Premiere CS5 later in windows 7.
Hope this helps.
Also Hats Off to Jon Barrie for his clear, straight and sincere words. This it what preserve the spirit of the forums like this.
Cheers!
