QT SYNC is a great app for adding TC burn. Or workflow is as follows:
Export a self contained QT movie of your sequence. (this GUARANTEES that you will be able to open it days/weeks down the road if you need to go back and reference the cut)
Open the new QT movie in QT SYNC and add the TC burn (you can pick size and location) (keep in mind you will need to know the starting TC number - if it is different than 1 hour)
Save that as a QT reference movie (it's only referencing two files - the self contained QT file and the newly created TC track)
Take the new reference movie into compressor and make your MPEG for DVD.
This process is much faster than having to render a nested sequence with the FCP filter - especially if you have to make approval copies with TCB of an online/uncompressed project. To give you an idea, we can make a DVD of our 1 hour show in about 45 minutes! The old way took about 2 hours!
Hope this helps.
