On Music, Yes I know what you mean, that's exactly how mine worked when I first got it. What DirectX version and Windows Media Player version do you have? I didn't do anything too complicated to fix mine, and I don't really know how I fixed it, but once I...
1) Updated my computer to the newest DirectX (even though it said it was up-to-date, I redownloaded the newest one and installed that just to make sure because its in the Samsung YP-T9 system requirements)
You can get the newest DirectX here:
In the center of the page under "Important Stuff" it says "Get the Latest DirectX Here". Go there and follow the steps it gives you to download and install that.
2) I updated my Windows Media Player. I had WMP10, so I upgraded to WMP11 and you can do this by going here:
and clicking "Download Now" in the center advertisement and following the steps from there.
Upgrading WMP helped me immensely, and it seems that once I upgraded WMP now Samsung Media Studio runs better too, but I don't know why this would have that effect. Anyways, I use both programs to transfer music onto my device, depending on my mood. I don't have to tell it where to go as long as I put my music under the "Music" tab on YP-T9, or just sync it over on WMP11 (going to SYNC at the top and just dragging music from the left, the library, over to the right, the sync list). It just files it into the correct spot on my portable player automatically, I don't know how it does this and why it didn't before.
Now my music is located under all the correct files that it should be. I can go to genres, artists, albums, anywhere, and it will take me to that list. And if I get to a song by going to Music>Albums>White Blood Cells (White Stripes), for example, than pick a song in that group, one neat feature is when I skip to the next track, it will only play songs in that album. When I just want to be able to skip to any random song in the entire music library on my portable, I just go to a song though "All Tracks" usually.
It works flawlessly, and the only thing I did was make sure every program I use with the portable is up-to-date, even if it was re-installing updates just to double-check. I didn't tell it to put my music in any specific location, or anything. It just does it by itself when I Sync it onto the player.
I really haven't ever heard of a YP-T9 recognizing the lyrics and showing them, I know mine certainly doesn't. It would be a cool feature, though, but I don't think these support showing lyrics.
If you are planning on trying it in the future, I have found that WMP11 always works smoother and faster over Samsung Media Studio when transferring videos onto the player.
I hope I have cleared up anything, and let me know if any of this worked for you!!
