After Google Reader gave up the ghost I switched to Feedly for my RSS needs. I like the interface, the ability to read by tagged collections, and the fact that it supports video feeds. Usually you can add a Youtube feed by searching within Feedly, but for lesser known channels you may have to create the link yourself.
I’ve searched for this way too many times, but this is how you add a Youtube RSS feed to a reader. Replace the below xxxxxx with the Youtube username and voila! Add that link to your reader and you are all set.
