Hi All

Anyone elso out there who gets so frustrated when seasonal DVD-collections of popular TV-shows are released with the first season(s) and then it just ends without any release of following seasons. I have started to collect so many popular shows which never will be completed due to the lack of interest from the television companies.
Here are some of those shows where the release of all seasons seams to have stopped for unknown reasons:

Alias Smith & Jones - only season 1 (of 3)
Green Acres - only season 1-3 (of 6)
McCloud - only season 1-2 (of 7)
Police Woman - only season 1 (of 4)
Have Gun Will Travel - only season 1-3 (of 6)
McMillan & Wife - only season 1 (of 5)
Baretta - only season 1 (of 4)
The Bionic Woman - only season 1-2 (of 3)
Emergency - only season 1-3 (of 7)
Hunter - only season 1-3 (of 7)
Quincy, M.E. - only season 1-2 (of 8)
Silk Stalkings - only season 1-5 (of 8)
Six Million Dollar Man - only season 1-2 (of 5)
T J Hooker - only season 1-2 (of 5)

Anyone who knows more of further releases of above shows on DVD ? Or will my collection for ever be uncompleted ?
Personally I think this is a little of "Highway Robbery" to lure people to start a collection of a favourite TV-show and then never complete it.
