Definitely not, to get 4 channels of audio on a DV tape you have to lower the quality (from 48 to 32) plus dealing with 2 tapes might be more trouble then what it is worth. Also do you have a DV timeline?
If your original timeline problem was missing render files you must have exported a NON self-contained files. I always set up my ETT project timelines myself. WHY, I want to save a buck. I get charged $150/hr to make tape layoffs (normally going to HD CAM) so I do all the prep work myself. But I also took the time to find out exactly what they need and I give them the cleanest files possible.
When ever I’m dealing with a new service facility I always have a short conversation with them to make sure everything is compatible and I understand what makes their lives easier. A 5 min conversation up front can save a bunch of time and money in the end.
