That's true in just about any endeavor.

Someday I hope to get to try that.  For now I'm living in a valley

topic threads are boring.  ;-)  I'll admit that I've ignored video
stuff until I started playing with Myth two weeks ago.  As far as I'm
concerned, my PVR-150 works very well for my purposes which is as a

things from this thread that I can apply and I thank all of you.
