I have spent numerous hours, I mean over 10 hours getting a good blogcast on IE 7 Beta 1. It seems that no matter what I do, I can't get it to run properly (the recording) and the video / sound is off or looks funny. Doing a blogcast on a beta version OS such as Vista is a real difficulty, but I think I got it. I have 2 versions I saved and tomorrow morning I will pick the better of the two and let everyone see it. Stay tuned.....
On the same note I want to say that Microsoft has made some serious changes in Vista. Doing a blogcat with the XP .wme settings don't work the same. You can't edit with Movie Maker! Not that I use it, but I tried and it won't work the same. Nothing is easy.... if you have not made a blogcast on Vista (and I don't think anyone has), you may want to wait until it is in standard production. Not fun, but if I can give you a preview, all the better!
