Most of the former tech TV hosts are very active podcasters.
You can find Leo LaPorte's many podcasts at
TWITKevin Rose does
Diggnation with Alex Albrecht.
Patrick Norton can be found at
DL.TVLeo does mostly audio while kevin and Patrick do video podcasts.
If you liked the Screensavers, these podcasts provide much more and they are free. Just subscribe to them in iTunes. I find that I spend much more time watching/listening to Podcasts than I do broadcast TV.
Incidentally, Call for help can be seen on the web as well... I think it is available on Google Video. However, there is a free way to see it as well. I am not going to post the URL to the torrent site, but I can say that Leo is aware of the site and quietly encourages U.S. viewers to use it. The show is owned by Rodgers Communications in Canada and they apparently know of the torrent site. While they have not publicly supported the site, they don't seem to mind either.... if you want more info email me privately.
