Date/time are lost when rendering to DV format

I'm working from a video in DV format.

Unfortunately, when I render the project to a file (in RAW DV format too), the resulting video has lost the original dates and time. The timecode is initialized to 1970-01-01 00:00:00

This is a problem for me, since I use this data to create subtitles (in .srt format) to be added to the DVD later on.

Is there a way to keep the timecode in the resulting video?
