Hi!
I'm glad we've had this exchange, because it IS screencast that's using flash. At least I've now put all the videos on YouTube.
Ironically, though, I've found more people were clicking on the original screencast link, and the bandwidth was getting ever closer to its limit. I have just purchased an upgrade so that the bandwidth is now 10x what it was.
To be safe, I'll put all future videos on both screencast and YouTube. I think, assuming folks can see a video on it (i.e. flash), screencast is better quality.
I'll be out today, so I'll try to get around to it tomorrow.
Thanks for this - I now know that screencast uses flash, and I will warn people to use the YouTube links instead if they have problems.
