tcpdump is a cli program that can output a file that Wireshark can read. It's a matter of copying an invocation from somewhere and having room to store the dump (external storage recommended, it might be a lot of data).
Thanks, I'll look into that. I would like to have a longer snapshot of what the Sony TV is doing.
Something I forgot to mention in my original comment -- that darn TV is accessing the Internet even when it is (supposedly) turned off. It's hard not be cynical about this stuff.
