It sounds like you're not using static IP addresses for computers and
devices on your network. When you rebooted your router it might have
assigned new network addresses for both your computer and the Roku.
I suggest before you do anything more, you make those local network
addresses static. You should be able to do that through your router
admin. Check the documentation for your router on how to do that. If
you don't do this you are going to have problems every time you
restart your router. Do this first! Unless you do this your router may
assign new IP addresses to either you roConnect computer or your Roku
or both and you'll just have to start all over again.
To eliminate variables I suggest you start completely from scratch
with the install. Remove the channel, remove the software and start
over. Take your time and follow the instructions to the letter (even
suggested directories) and use only the test movie. Make sure auto
IMDb is off.
Index the test movie and try it. If it works, only then move on. Add
another movie and test. If that doesn't work then there's probably
something wrong with that movie file. Add each movie one at a time and
test.
Personally I have enabled port forwarding for the roConnect computer.
I'm not sure exactly how roConnect works, but since all this is on a
local area network (except IMDb) you probably don't have to do this.
P.S. Unless you have a network enabled TV (rare - but available), your
"TV" does not have an IP address. I am using a regular old analog CRT
TV. You don't need a TV with a web browser.
