I agree that all the formats it supports from playing from a CD/DVD should also be supported via the network. And it's true that 3.11 support is a bit buggy, and that the PC Link software is very basic. The firmware also needs updating to give it full functionality over the "new" formats such as fast forward and rewind. However, for all these faults, this player is worth it just for the ethernet connection. Having access to my 43Gb of MP3s on my proper hi-fi setup downstairs is brilliant. The sound is great, and it's so convenient to download a track and listen to it properly without having to burn a CD. By the way sorti, there is no need for Gigabit ethernet. Even if it did support MPEG2 via the network, the max bitrate allowed by DVDs is 9.8Mb/s and a 100Mbit connection = 12.5 Mb/s so no problems there.
