I have the Pioneer DV-F727 and have them Daisy changed and they work great (max is 2). 600 DVD though makes me nervous since it get's pretty hot in there. The down sides of this are:
- No more than 2 Daisy Changed
- No progressive scan
- Can only do S-Video
- Both units are On when you power up (your DVD's stay nice and tosty).
That's my only complaints, but I am happy with the setup for now and it's cool to have most of your movies at your fingertips.
Once I upgrade to an HDTV, and am going back to single disc player with progressive scan and a DVD rack.
Sony is comming out with a New 300+1 DVD changer in Aug. that's progressive scan.
The Kenwoods DV-5050 and 5900 have to many issues with the GUI, the layer change, and the Entre Hub. It's not worth money and the hassle
