Bah I just wrote a massive and impressive reply, only to find my ISDN had disconnected...
The jist of it was
a) I looked into this and can't remember, will go look now
b) I'm not keen (although feel free to challenge me) in videos because they are very bandwidth intensive. We are currently using half our allocated bandwidth monthly and it's growing.
I will go see the settings but a 50mb video, I think we get 6gb bandwidth a month, upload that video once, download that video 122 times and voila all the months bandwidth gone
What I think would be a good idea is if people found their own places to upload the videos (sorry to be stingy but I'm trying to keep the website's yearly overheads minimum) and then we started a thread with video links in it...
I'll go see how I set the gallery up and about what bandwidth we get.
