Image super EPG and channel list Mist

After I connected the unit, I was impressed by the image that sort of programs found is very tedious and cumbersome, the same applies to the EPG of
very slowly lists and not much information.
USB sticks have to be quick otherwise recording is not possible, hard drives without a separate power supply (2.5 inches) also do not work.
Except for the CI slot, the other bays Blind.
Have returned because it was unable to start the unit.

Addendum: I received today the replaced unit with the latest firmware, it now recognizes the hard drive (2.5-inch) and timeshifting is also possible, you can even jump when shooting at each section of the video without affecting the recording. Unfortunately, the EPG has not improved, the call are only partially available information and it is painfully slow.
Also sorting the program list is very cumbersome and unreasonable.
Energy consumption makes in my operating 24Watt and corresponds to the average.
