I am using WDtv live to stream wirelessly from you tube. It will run for awhile but at some point: an hour or so, the unit will just stop and reboot itself. I have firmware 1.13.18. ( On 4 other units I had updated to 1.15.10, but that just caused the units to go into reboot phase- no oppurtunity to even roll back or re-set to factory, but THAT is another issue).
Does You tube time out?
