YouTube and the Yolngu Zorba

I saw Zorba the greek Yolngu Style on the television news a few weeks ago and thought I would use it as my YouTube example as it loked awesome. Sadly, it was very broken up by the video stopping and starting every ten seconds or so which was very disappointing. I'm not sure if that's our poor bandwith or what here at work. As I wanted to see if this was the case on all videos on YouTube, I decided to search for...you guessed it, Pavlov's Dog. There are a number of videos with PD performances, particularly from the recent Greek tour. However, the same stop/start affair occurred. The sound on Julia was actually pretty good although it was nearly impossible to see David and the band. But I then tried Theme from Subway Sue which was absolutely abyssmal. And again the video stopped and started every 5 seconds or so. Unwatchable and unlistenable. How can anyone watch this stuff! We could not use this in a library setting unless whatever bandwith or other issues are causing the problems are fixed. It's just crappy otherwise.
