Top functionality, but two strong for improvement things

The drive is also fairly quiet, even though it is still perceived with a (silent) high-pitched tone when unfortunately CD playback.

The start time is acceptable. This can be shortened with option to a few seconds, however, the device consumes more power then in standby also.

At the functionality of nothing there to complain about: There are a lot of video services support (eg Youtube, Amazon Instant Video maxxdome, Tagesschau), additional media information check (switched off) via Gracenote. IPv6 supports the player also already. DLNA is also there. Since, however, I noticed that the DLNA server (in my case a FreeNAS system) should run quite a few shake, otherwise no compatible files are found. My old Asus HDP-R1 was there faster. Playback is great though and runs without problems.

A few downsides there yet:

1. As some reviewers responded (and a certain Mr denied), finds except for DVDs / BluRays a forced conversion of the material to 60 fps instead, which can lead to unsightly micro stuttering. This simply is because the loving does not switch the player on the frame rate of the source material but remains at its 60 Hz. In imaging devices (in my case a beamer), which can display the current resolution / refresh rate, can relate to that very well: Identical source files (from the DLNA server); My Asus HDP-R1 switches the frame rate to (depending on the source material 24,25 or 60 Hz), the Sony remains stubbornly at 60 Hz. Since this behavior does not exist in DVDs / BluRays, I'm assuming that it with a firmware update could be resolved. Sony Support I have therefore already contacted if enough people do the moves because maybe something.

2. In addition, the player does not support the exFAT file system. That is, the outer thumb drives larger than 32GB ago remain, unless they are formatted with NTFS. Also could be safely solved with a firmware update. But since one (to my knowledge) has to pull the trigger royalties to Microsoft for it, I doubt something if there is a support will come.

3. The buttons on the device itself are very rare - there is only one standby and an eject button. Here I would have still desired buttons for Play / Pause, Stop, Forward and Back, which it would be at least in the operation as a CD player an advantage.

Additional 29/8/2014: I measured it twice with a power consumption meter: In operation (CD), the device consumes approximately 10 watts, 6 watts at idle, in standby with quick start enabled 5 watts in normal standby less than 1 watt (!).
Our Sony fanboy is that but probably doubt and claiming the device consumes no electricity but producing what ;-)
