Hi ckeith990,
I am not sure if you found a solution to your 1) problem, but I ran into this over the holidays and this was my solution.
1) iTunes Match won't stop loading on Apple T.V. meaning I can't access my music library. This has been going on for two plus weeks. Based on other posts there are many people having this problem. Is there a fix?
Solution
On iTunes
1. Open iTunes on your laptop/computer
2. Turn off iTunes Match
3. Sign ID out of iTunes ID: Menu>Store> Sign Out
4. Don't close iTunes (we'll go back to it later)
On your Apple TV
1. Sign out of your WiFi network: Settings>General>Network>Wi-Fi>select your network>click Forget Network
2. Restart: Settings>General>Restart (not reset)
3. Once restarted, Sign out of iTunes Store: Settings>iTunes Store>AppleIDs>Sign Out
4. Restart
Note: If you can sign out of your Wifi and then your iTunes ID at the same time - go ahead. For some reason I couldn't because iTunes Match was trying to load.
5. Your Apple TV should only have two icons now. Settings and Computers
On iTunes
1. Sign in with your ID.
2. Turn on iTunes Match
3. Allow computer.
4. iTunes Match will connect to the Cloud and update your music.
5. Do not close iTunes
On your Apple TV
1. Sign into your WiFi network first
2. Sign into your Apple ID
3. Turn on iTunes Match: Settings: iTunes Store>iTunes Match On
4. Go to the Music Icon on the Apple TV Screen - it will load.
After it loads you can close your iTunes on your computer. Now I am not exactly sure if it matters to have your iTunes open on your computer, but the first time I didn't and I was stuck loading for days. The second time I left it open, iTunes Match loaded on my Apple TV in a minute.
Your basically signing out of everything resetting and signing back in.
Hope it helps.
