I haven't actually watched them yet...but I intend to do so this month. There's 3 episodes on this DVD, 1. Deadline at Noon, 2. Flash Gordon and the Planet of Death, and 3. Flash Gordon and the Brain Machine.
All reviews I've read of 'em aren't very complementary, which is why I'm not in much of a hurry to watch them, but I've set my goal to watch them this month.
One thing I like to do when looking at a DVD is to check out the DVD's set up - their 'main page', and the design of all the other pages. The Flash Gordon dvd was put out by a company called DVD Video, or mebbe it's called DigiView Productions.
For a dollar DVD, it's got some nice menus.
