Been a while since I came back here. Forgot I posted this. The lock up issue was a problem with the unit. I contacted Yamaha, and described my problems. The engineers said the hard drive wasn't formatted correctly, but who knows. I returned the unit, and was sent a new one.
The replacement unit has been working trouble-free since I got it. Almost 1200 songs on the hard drive, and I'm still trying to get all my stuff in there. I even had an update CD sent to me by Yamaha. The updates are supposed to allow album cover art to appear when the song is playing.
I don't have any playlists set up, but you can set them something like 100 of them. I prefer to just use the random and let it run. It's cool to hear music that you haven't heard in a while. I had hundreds of cd's that I never listened to anymore. Now, it's cool to just let it play.
It's pretty easy to upload the cd if you just want to put the whole thing in there. I prefer to pick the songs I want off of each cd, so I don't have to listen to the tracks I didn't really care for. If you store the songs this way, you'll never run out of room, I would think. I set the MP3 quality to the highest setting, but I haven't used the MP3 version. It dually stores both PCM, and MP3. You can delete the PCM copy anytime after storing. I'm just going to leave the PCM's alone unless my hard drive fills up. Then, I'll go back and pick which songs won't make much difference between PCM and MP3.
I don't use the client feature. Don't know if I ever will. But it's certainly a cool thing. You can set up your home computer, or buy one of their remote stations and have complete access to all of the music on the hard drive.
My biggest challenge has been trying to set it up through my wireless network. I can't use the internet database yet. My cable modem is upstairs, and my stereo set-up is downstairs. I have tried, without success, to use a wireless access point to have this feature. I still don't have a clue. I'm sure it can be done, but I need some kind of networking pro. If you have a router that can be hard-wired to the unit it should work fine.
If anyone can help with getting this thing set up wirelessly, let me know!
