Important to me was the easy availability of different libraries of ER-TV channels and the integration of Youtube with my own account there, including the channels..
The ÖR libraries are available and offer (partly) the possibility there to create their own favorites, which I find very good.
However, the built-in YouTube app no longer works. This seems to be due to an update by Youtube. An adaptation of the device firmware (have the latest up-played) seem to be of needs in order to use Youtube again can. Therefore, I hope that there will soon be an appropriate firmware update here.
The ordering of existing apps is quite cumbersome. So each app must be moved individually, are then stored in the desired location and then again select Save. If one does with multiple apps in a row without the device off in between, it can happen that make apps again on ursprüglichen place are, after restart. This is annoying and time-consuming because of the start up procedure takes about a minute even.
I am satisfied but with the HD capability (upscaling) of the device. Such programs are very well presented.
Tied I have the device via LAN, so I can not comment for optional WLAN. In a 6,000 DSL line I've noticed no dropouts or stuttering.
