Well it really depends on what your after, alot of the fritz trainer vids are mainly based around opening play however they do have tactics (mike Wells) and a Postional vid (Jacob Aagaard) There's an end game one with some German guy which is quite good however he does tend to go a little fast.
Rustam Kasimdzhanov has got 2 DVD's coming out dealing with tactics, check out the chessbase site for release dates on them

Alot of the Andrew Martin vids are good, he comes across as a good bloke and can be funny. I've also got some of the DVD's from Gary Kasparov however for me there not as good as the Fritz trainer vids mainly down to Gary not being as fluent as the other chess players, he tends to oh and ah's alot when talking which can get a little annoying.
As I said though if you want a sample I can upload one of the videos so you can get a taste for it.
yea, the adrew martin videos are really entertaining and good. he's very sarcastic and drives the point home in memorable ways. "...what happens? -you get murdered in your sleep, that's what happens."
the karsten müller endgame dvds seem very good also, very informative. and the guy just cracks me up, he's everything you'd expect from a german monty python character. π
