I also have first zig "NoName" player bought only to find that they either go broke shortly after the warranty period, or exchange times just takes 3 months. To put an end, I decided once to buy a more expensive player. The acquisition was worth it. The Panasonic does pretty much all formats, the menu can be conveniently and easily configured, the picture quality via HMDI and Component is razor sharp, the drive super quiet. The optical output was not really missing, the digital coaxial output is enough perfectly to a powerful audio output via matching AV Receiver and vicious surround system to create.
The most important functions can be via "Viera-Link" on the Ferbendienung the Panasonic TV set control (Play, Pause, Skip, On / Off), but I use rather remote control of the DVD player, just out of habit.
