Summary Bought two of these wonders almost two years ago. I first bought the Sony 300 disk unit. After the Sony twisted and jammed about 5 DVDs inside of it I returned it bought the Pioneer units. Haven't had any problems with them at all. I use them for only DVD's and only have 15 empty slots open. I guess that it's time for a third.
Pros Stores a lot of DVD's and CD's - you can input titles and artists, and it even remembers the name and artist of the DVD or CD if you move it to another slot. On-Screen listing of titles handy for finding desired CD or DVD.
Cons Limitation of 12 characters for title and 12 for artists is too small. Should be 24 characters each. Sorting through the library is hard because on-screen display is limited in number of titles displayed and paging is awkward. Also a bit too wide.
Summary This is by far the best juke-box style DVD or CD storage device I have ever seen. Problems I had were that it was too wide for my racks and I had to remove the wood trim on the side, which makes it look a little weird.
You should also know that the device is very deep, and when you add in the clearance needed for the connectors at the back, it barely fits into a standard cabinet, and will not fit into many of the less expensive cabinets because they are not deep enough.
Another serious shortcoming is that it only allows 12 characters for the title of the disc and 12 characters for the artist. You have to abbreviate almost everything, which is a nuisance. 12 characters is simply not enough - it should allow double this amount. I also wish it allowed you to put the names of tracks on CD's, but since it is primarily marketed as a DVD player, I guess that is acceptable.
When trying to find a DVD or CD using the on-screen display (which is a feature I like), it only displays in groups of about 5 at a time. Instead of just toggling down through the CD's and DVD's and having the next screen pop up, which would be the intuitive way to move to the next page, you have to use the 'next chapter' key on the remote. This seems silly and frankly is very awkward to do.
Also this device does NOT PLAY 3-D DVD's. I had to purchase a second device for the 3-D DVD's in my library.
I have also had a minor problem with some DVD's - for some reason it seems to eject some DVD's in the middle of viewing them. Then when I reload the DVD, it plays OK sometimes but not always. This is a pain if little kids are watching a Disney DVD and it suddenly stops playing; the kids start crying, and it is almost impossible to get the machine back to the spot where the DVD crashed, and even if you can, it then sometimes crashes again a short time later. This is a pain when adults are watch DVD's too.
Also some commercial DVD's just will not play in the machine - I have about 100 DVD's, and only one or two will not play, but I have no idea why. They play fine in other machines, and they are commercial DVD's - not DVD copies or DVD's made at home.
I have read that it is vulnerable to room vibrations and noise causing the DVD's to skip, but I have not experienced that at all. However, my floor is cement - perhaps that might be an issue on wood floors. Not sure.
So, except for these minor annoyances, the machine is really nice. To be a perfect machine it needs to add these features;
1) Internal electronics with an HDMI output that can handle 3-D DVD's,
2) Display more characters for the title and artist,
3) Display the title of CD's when they are playing,
4) And my personal wish - maybe too much to ask - would be to display the songs on the tracks when playing a CD (even if you had to manually input the song titles).
5) Do something to minimize the problem with rejecting a DVD in the middle of displaying a movie - make it more foolproof or something.
I consider those to be the shortcomings, but even with these shortcomings, there is nothing else out there that I have found that even comes close to this product.
Pros Great player, excellent indexing of discs
Cons No HDMI output (technology is too old).
Summary Without doubt the best there is in that category. Am about to get number 4 to accommodate all my movies.
There are no others that can do what they do.
