Yes, hello indeed, welcome to the site.
Well. Erm. Most of his stuff seems to have been for the BBC. So you'd need to contact BBC Worldwide about that really, with 2 entertain (their DVD distribution arm) as second. Only three shows,
Thirty Minutes Worth,
My Name is Harry Worth, and
How's Your Father? were on ITV, being
Thames, Thames, and
Yorkshire respectively.
For the Thames shows, you'll need to contact talkbackThames, and Yorkshire are now part of ITV plc, so they're the first point of call for
How's Your Father?. Beyond that,
Network seem to handle ITV's "classic" output almost exclusively (particularly Thames), so they'd be next.
Hope that that is of some help.
