Colin, you are right: it is possible to modify metadata (Timecode or Date/Time) with the demo version of DVMP. I mixed up the extraction of metadata and modifying since trying to extract metadata comes up with the message 'this feature is only available in the FULL version of DVMP Pro'.
I myself came across the issue of finding the date when the scene was captured. Have been looking for a long while until i came across this discussion.
I didn't need any fancy stuff, just find out the date when all my imported scenes wre captured. Thanx to Bill Hunt's suggestion, i downloaded the older free version of Scenalyzer, and it did exactly what i was looking for.
I just registered so that i can say thank you for your suggestion.
