Running Mythbuntu 7.10 on amd64. I have mythstream selected in the Mythbuntu control panel, it seems to work OK.
I suspect however it isn't the latest version. For example, I don't appear to have a youtube parser as described on the Mythstream website under 'New in v0.18_1':
How can I prove what version I am using?
How can I upgrade if it is required?
