It should be relatively straight forward to add VDR recording meta-data support to mediaserv (and would seem to link up nicely with the live VDR interface you're doing). I've already got some information on that already (thanks to luca), but without a VDR system to play with, testing's obviously a bit tricky.

If anyone knows Perl, fancies hacking on mediaserv and has a VDR system to play with; please get in touch: it'll get done much quicker if we're scratching your itch.
