Since the latest YouTube update on my 1st-gen Sony Blu-Ray GTV, many times while I am watching YouTube clips, behind the scenes a subscription will update itself and then the video feed stops playing. I get the error message: "There was a problem with the network." Or "could not verify the user." I sign out and sign back in, to no avail. I have to reboot GTV and start over. More than annoying. It seems like everything is always in beta with GTV. ps: Occasionally, when YouTube is in the background, an option pops up to force quit YouTube and that helps. Is there a keyboard command to force quit YouTube? So I dodn't have to reboot the entire system.
