This is Mash TV which streams non stop mashup videos (over 9 hours worth at the moment) click play to start, there is also the option (on demand) to choose individual videos to play
This software is still in beta - if you have any problems with it streaming please let me know on the comments page, it is a bit bandwidth hungry so you will need a decent connection.
Be patient it takes a while to get going sometimes!
There is an alternative player here - same videos different process
