thanks for all the help guys, it is appreciated.
I have found an app for the mac for downloading you tube vids, but as Paul says, the original will likely be higher quality.
If I can download from Paul's Dropbox folder, I can download from anyone's! in theory. The reality is that my connection is dodgy, but I'm willing to try if you are.
What I'll do is email those of you who have already said you have material. if you don't have a folder, the link in it will show you how to set one up for free. And we'll both get extra free storage into the bargain!
Anyone else joins this thread, just mail me and I'll share the details.
if anyone has a link to software that gives me more than 24hours in a day, please send it ASAP
