Hi superj.
You'll like TC once you get used to it :-) I struggled at first too, but with help from forum members, I've got my TC machine (well, one of them ;-) ) running very sweetly (and very fast!)
Ditto what Rich says about Flash. I use OSS for sound on YouTube, and have no problems. I used the App Browser to download OSS and ossxmix (as On Demand apps), and when I want to watch and listen, I start oss, then ossxmix, get the volume level set properly, then start my browser, and I get sound with the Flash videos.
