You are not going to want to use the Network Media Player as a NAS server due to its poor network performance. The player has just enough bandwidth to stream data but I wouldn't even attempt to use it to store file on to watch on other computers. For comparison a single drive in the new QNAP TS-809 Pro averages around 60 MB/s. I really can't see why Raidsonic didn't make sure the 10/100 Ethernet was a Gigabit connection.
The remote control is the mechanism that gives you control over the Network Media Player and depending on how you look at it the remote could be considered the most important part of the kit. It is certainly important enough to make a benchmark out of its performance.
To name folders on the Network Media Player you have to use the cell phone style letter input system from the remote or attach a USB keyboard. The play, stop and pause buttons are all the same size and it will take you a little while to get use to their location.
