Very easy to reproduce.
1) Enter a channel (any channel...say Netflix)
2) Using the External Control Point API, issue a command to take the user to the Channel Store, to a specific channel
For instance...take the user to the Hulu Plus screen in the channel store by doing a POST to:
http://192.168.0.29:8060/launch/11?contentID=2285About 70-80% of the time, this causes the box to lock up and (very slowly) reboot.
I have confirmed this on 2 boxes (an LT and an XD). Both were fine wrt this prior to today's firmware update.
Roku...can you reproduce and comment on an ETA for the fix? Having a total hard reboot from a simple command is really bad.
