make sure you've downloaded the zip file pointing to the Beta version of the next release. As mentioned by machavez, the eariler version does not support music at all.http://s3.amazonaws....ect/ec111b2.zip
Second, sounds like you've been tweaking the "Content" tab a bit.
You might try starting from scratch by removing all those shared folders you've got, and then adding back only the iTunes and iPhoto default folders (not any direct stand-alone folders like iTunes Music, etc. ) to start.
Make sure you DO NOT alter the name of the iTunes folder when you add it back.
Start Eye Connect running again, then test the HR-20 to see if your computer shows up, and hopefully just one
If it's talking to the HR-20, there's nothing wrong with your port/firewall settings.
I suspect what you've been seeing is a list of songs on the left side of the TV screen, with only "Hot Tips" or whatever showing up in the larger portion of the screen. If you see this, your music will not load. Your playlists, albums, podcasts etc should show on the left, and the track list inside those playlists should show up in that "Hot Tips" larger portion. Now it will work. Press STOP on the remote to stop the track and return to HR-20 channel audio.
For iPhoto, once you've added back the default iPhoto content (again, do NOT change the name of your iPhoto content), go ahead and go back to Content tab and add the iPhoto folder again, except this time give it another name. Keep both of those folders.
Just like iTunes, you should see iPhoto albums populating the left hand side, and a list of the images themselves within that Album populating the larger portion of the screen.
