I've started getting error tvq-pb-101(3.3.-302) on my Tivo when playing Netflix. It plays between 5 and 20 minutes before it hangs and displays the error code.
I reboot/check network the Tivo but it keeps doing it.
Thanks for posting and sorry to hear you've been having some issues with the Netflix app,
Are you going through the Home button or via the channel?
Has there been any change since your post?
