Encoder and scale options for Sony Bravia eg. EX500

Hello

In beginning sorry for my english.

I spent a few days testing the PS3 Media server settings on Bravia EX500. This TV is limited to 20Mbps MPEG2 stream. To get the maximum quality of what is possible for this TV (MPEG2 <20Mbps) hooked the parameters of the resolution of the source material. Bravia also has problems with the correct aspect ratio setting. I decided also to scale the materials of poor quality to 720p (enhanced overall image and better subtitle font).
I wanted to share my thoughts could be useful for someone or author implements the program settings.

The command works on C2D T9500 (including 1080p)

The maximum setting (LAN cable or very good, no distractions Wi-Fi Draft N):
((double) width / height) >= 1.7 && ((double) width / height) <= 1.9 :: -mpegopts vaspect=4/3
((double) width / height) >= 2.3 && ((double) width / height) <= 2.5 :: -mpegopts vaspect=221/100
width * height >= 1000000 :: -quality keyint=25:vqscale=1:vqmin=6
width * height < 1000000 :: -quality keyint=25:vqscale=1:vqmin=4
width < 1280 && ((double) width / height) >= 1.7 && ((double) width / height) <= 1.9 :: -vf scale=1280:720
width < 1280 && ((double) width / height) >= 2.3 && ((double) width / height) <= 2.5 :: -vf scale=1280:544


Safer settings - lower bitrate (for a good Wi-Fi):
((double) width / height) >= 1.7 && ((double) width / height) <= 1.9 :: -mpegopts vaspect=4/3
((double) width / height) >= 2.3 && ((double) width / height) <= 2.5 :: -mpegopts vaspect=221/100
width * height >= 1000000 :: -quality keyint=25:vqscale=1:vqmin=10
width * height < 1000000 && width * height >= 600000 :: -quality keyint=25:vqscale=1:vqmin=6
width * height < 600000 :: -quality keyint=25:vqscale=1:vqmin=4
width < 1280 && ((double) width / height) >= 1.7 && ((double) width / height) <= 1.9 :: -vf scale=1280:720
width < 1280 && ((double) width / height) >= 2.3 && ((double) width / height) <= 2.5 :: -vf scale=1280:544


((double) width / height) >= 1.7 && ((double) width / height) <= 1.9 :: -mpegopts vaspect=4/3 - improvement proportion 16:9 on Bravia
((double) width / height) >= 2.3 && ((double) width / height) <= 2.5 :: -mpegopts vaspect=221/100 - improvement proportion cinema (?) 2,39:1 on Bravia

width * height >= 1000000 :: -quality keyint=25:vqscale=1:vqmin=10 - options for 1080
width * height < 1000000 && width * height >= 600000 :: -quality keyint=25:vqscale=1:vqmin=6 - options for 720
width * height < 600000 :: -quality keyint=25:vqscale=1:vqmin=4 - options for poor quality

width < 1280 && ((double) width / height) >= 1.7 && ((double) width / height) <= 1.9 :: -vf scale=1280:720 - scale poor material (< 720) in 16:9
width < 1280 && ((double) width / height) >= 2.3 && ((double) width / height) <= 2.5 :: -vf scale=1280:544 - scale poor material (< 720) in cinema format

why PS3MS first tab displays the physical bitrate * 2? I checked my router transfers and it was less than half of the PS3MS.

Thank you for your comments
