Eval ADV8005 Analog Output scaling problem

Question

Hi, 
 I am scaling a 1024x768@60p DVI video input to an analog 576@50i output (with EVAL ADV8005-8N). 
 command used: 
 -src HDMI 1 
 -mainvsp 576i50 
 -out comp 1 main 
 The conversion has the following two problems: 
 1) is present a bar on top of video that is not related to image (enlight in red in image) 
 2) the video is cut in all the direction ( enlight in green in image) 
 do you know where can be the problem? 
 NOTE: I tried with two different monitor and the result was the same 
 Some update: 
 - we discovered that your script use the ED encoder even if the video is 576i50 (that is SD standard not ED). why you use ED encoder and not SD encoder? This can cause the problem that we are seeing on screen? 
 -we tried to use SD encoder and the conversion using SD encoder is good, no more cut or strange bar on top of video, but in SD mode we are able to go out only with YPbPr mode not in RGB. if we try to set RGB as output the signal is corrupted (no good signal avaiable on output). 
 below the setting we use: 
 i2c16w 1a e828 10 
 i2c16w 1a 1a04 22 
 i2c16w 1a 1a05 00 
 i2c16w 1a 1a06 04 
 i2c16w 1a 1a07 6c

 i2c16w 1a 1b44 07 
 i2c16w 1a 1b45 06 
 i2c16w 1a 1b46 08 
 i2c16w 1a 1b47 00 
 i2c16w 1a e881 ca 
 i2c16w 1a e884 00 
 i2c16w 1a e883 88 
 i2c16w 1a e882 11 
 i2c16w 1a e844 02 
 i2c16w 1a e845 C0 
 i2c16w 1a e846 02 
 i2c16w 1a e847 40 
 i2c16w 1a e84B 00 
 i2c16w 1a e849 10 
 i2c16w 1a e64b 11 
 i2c16w 1a e649 10 
 i2c16w 1a e401 00 
 i2c16w 1a e42a 25 
 i2c16w 1a e42b 34 
 i2c16w 1a e400 1E 
 i2c16w 1a e4e0 00 
 i2c16w 1a e402 10 
 i2c16w 1a e487 20 
 i2c16w 1a e828 11 
 i2c16w 1a e828 13 
 i2c16w 1a e828 17 
 The register that we use to set if RGB or YPbPr is e402 and we have the following behaviour: 
 i2c16w 1a e402 10 -> the RGB is set but no video on output 
 i2c16w 1a e402 20 -> the YPbPr is set, video on output OK 
 we tried also to put register e487 at 0xa0 ( so enable SD RGB input path) but with these enable on output we have only the synch whatever is the value of register e402 . 
 Even with CSC enable on register F418 as suggest in another post the result is the same (no video output with RGB enable).
