We appreciate your patience regarding this matter. I understand that your Roku device freezes every or after commercial when streaming Xena Warrior Princess through The Roku Channel, is that correct?
A few questions here to better understand what you're experiencing. Are all other streaming channels playing content normally? Does this happen on all movies/shows in The Roku Channel or just Xena Warrior Princess? In addition, have you tried removing The Roku Channel from the Roku home screen. Then, restart your device. Once it loads up again, add the channel back once more and try playing content again?
We look forward to hearing from you and assisting you with your needs. Thank you!
