	Ok. Now everything make sense.

	I really appreciate your work, so I wouldn't say that it is shame on you. And 
who knows, maybe one day we will have DVD Max feature for G-Series just 
out-of-the-box! ;)

	Maybe you should try to watch some move on a big (72cm or bigger) screen! I 
think that after that experience you would care. I haven't cared about tv, 
the same as you, for very long time but when I saw a movie on it I've changed 
my mind.

	Thanks for the information. I really appreciate it.

	Mga_vid is working for me for about 2 years like charm. Until now there 
wasn't a single problem! :)
	The reason why I bought Matrox is the myth that it is best supported graphics 
card for linux (especially G series). However, for me it is just a myth 
because from time to time I have problems with my dvi connection, and well 
known maven encoder specs were never released in to the public. But, when I 
hear the stories about other companies graphics cards I consider myself 
lucky. ;)
	Ones more. Thanks for the information!
