Comment 21 for bug 403859

I tested it also in vlc and all seems to work ok, so I think the problem may be just Rhytmbox specific.

Also because vlc seems to handle some movies better than Totem (which for some movies have a problem with sound, making pulseaudio consuming CPU performance and than hang), I'm considering to switch back to vlc, to have just one player for all. As I searched there is a lot of bugs reported for pulseaudio, but on my system it seems that mostly only Rhytmbox and Totem has problems with pulseaudio, which is strange - since those are default apps for Ubuntu and should work better than alternatives... but I guess it would be to easy and perfect world to live in:).

Anyway if you want me to test something more let me know. I plan to have Rhytmbox+Totem in my system for some time before I completely replace it with vlc.
