Thanks very much for this but as a not very techie, techie, I'm not sure that it answers my question? Part of my reason for using PD is to provide other people with short (30-40 mins) videos which I currently do via DVD. With my ancient PD version and steam driven laptop, this is easy. I can then "produce" and archive the films for myself and store them on an external drive.
If my new laptop doesn't have a disc drive, my question is - how do I use the new version of PD to achieve the same thing? The people I produce the DVD's for currently are not necessarily "friends" where I can share the film on Facebook or whatever ? Is the only option via Youtube? Not sure that would suit some of my "customers" as they prefer to watch on a TV and not all have the facility to connect TV to internet ?
