Using KDL32EX521

Having recently purchased this TV here are some facts:
Very good and beautiful material, see the reliability in time.
Qualitée flawless picture pretty intuitive user-friendly menu, super EPG.
The sound power level is correct seen the little HP, of course this is not hi-fi.
But it is the same for all LED TV too flat for speakers worthy of the name.
SCART, 4 HDMI, 2 USB ports (one dedicated to the Rec. HDD) component jack, headphone, PC ... is complete.
In fact you must enter the HDD on TV (max 8 disks) that formats the HDD and careful, effectuéss beings recordings can read that on TV! it owns. I plugged in an SD card (via adapter) with AVCHD h264 format film) on a USB, I could play movies despite qqes annoying pixels bottom right of the screen (AVCHD decoding carne?). PIP (picture in picture) although but with two different inputs (HDMI, AV, TV ..) unfortunately there is only TV tuner can not therefore see two simultaneous TV channels, a second tuner would have been the must especially if a chain is recorded (HDD) to be able to watch another.
The TV could not read mpeg2 files stored on a USB key via a TNT 40 adapter.
Files are seen but not read? to be continued ...
At the network level (LAN RJ45) I plugged into my router OK Web access.
For Wifi requires a sony USB key Wifi course ...
To access media files from PC LAN (WiFi or LAN) they must pass through a DLNA server.
Win Media Player 11 (xp) or 12 (seven) is integrated DLNA server I think that should be configured.
The explanations of the i-Manual built into the TV about it is insufficient for a novice.
For simplicity, it is sufficient to pass through a small multimedia box (with or without built-in HDD) to play all formats (supported by the case).
