Decklink HD for offline solution?

Hi. I'm new to Premiere Pro 2.0. I'm half-way through editing a long documentary and we've run into major problems due to digitizing offline footage with older Matrox cards. The timecode got messed up when we upgraded to 2.0, but we didn't realize it at first. Now we've done a lot of editing with bad timecode. I'm trying to figure out if we can port the project over to Decklink cards somehow. We have one Decklink HD card right now and may purchase more. But we don't have the budget for huge RAIDs, so we want to use the Decklink cards with offline DV footage and then online with uncompressed HD via one of the cards. Can we just use DV footage as offline sources with Decklink cards and then redigitize the same footage into uncompressed HD from the Premiere project (as opposed to an EDL). If so, can we edit the same project with offline DV footage on other stations without Decklink cards? The footage was shot with a Panasonic Varicam and digitized to a DV codec (Matrox version). Is there anyone using this kind of workflow?

Any help is greatly appreciated? Thanks!
