OK, so after much time off from my project this summer, I'm finally at the stage where it is no longer in the shop and is in use. The TV didn't come until early August, so I needed that to get motivated and finish this thing.
Here's the basics on my project. 80x 22x 24 made of oak ply with veneer edging for the shelves and oak trim for the edging on the unit.
5 sections -- 2 for DVD/ CD pullout drawers, 2 for components and the center which originally was going to have no doors has the center channel speaker and Sat receiver.
Doors are panel doors I made with a slot cutter on a router, and joined with small biscuits. I used 1/4 inch solid oak for the cd doors and 1/4 inch tempered smoked glass for the 2 component sections.
The center speaker cloths insert was an afterthough. I actually just used L brackets to hold together a 1 inch frame and then stapled the speaker cloth on. The frame is held in with insert/ roller brackets ( or whatever they are called).
Hope this inspires others who've never done woodworking before to take the plunge. I certainly made some mistakes along the way, and probably wasted more than $100 in wood, but the finished product is worth the effort.
Thanks much to Ron Stewart for helping with advice and links to sawguides and of course to Ironhorse and everyone else who has contributed so much to this thread.
