Glad you found them useful. Unfortunatly I didn't record the other presentations as I headed into town to do some shopping (and find lunch).
In reply to bucksboy:
The flash side of things seems to work in Oregano 3, but all it ends up doing is downloading each chunk of the video, finds out it doesn't support that video format, and then throws it away and fetches the next section. So until someone makes/ports the appropiate codec to RISC OS its unlikely that its going to be working any time soon.
