Having watched both the US production from May 2003 until its cancellation in 2004, as well as the New Canadian produced version since its inception in August 2004 I think I am qualified to state that the new version is even better than the original.
Even though the shows are no longer "live" the Canadian production has had more in-depth coverage of topics that are of benefit to the more advanced user. Andy Walker, in particular, seems to favour covering topics that are a little "geekier" than the norm on the old show.
Amber McArthur's web workshop segments are also very interesting and informative, even though I do not have a web site her comments on designing and planning web sites are excellent.
The new MS Office experts are knowledgeable and give very good tips.
The show has recently re-introduced the segment by Alex Lindsay on Photoshop which promises to be excellent as well.
G4TechTV Canada seems to have made a genuine commitment to the program and it is getting better and better as they become more familiar with the technical requirements of producing a "How-to" kind of show.
