Dottor Kildare

I used to watch this show (along with Ben Casey show) which was on around the same era, and loved them. This was in the 1960's. I watched

Dr. Kildare every week starring Richard Chamberlain. It was a must for me. And Raymond Massey, as Dr. Gillespie was really the best actor in the series. I always thought Richard Chamberlain was a good actor and his career has gone well through the years. But as far as I am concerned, I liked him best as Dr Kildare. Why did they never bring out some episodes of Dr. Kildare on DVD or VHS?There must be lots of us still around who were young in the 60's who would buy them.
