Ok the useful bits for me are

(II) CHROME(0): Printing DDC gathered Modelines:
(II) CHROME(0): Modeline "800x600"   40.00  800 840 968 1056  600 601 605
628 +hsync +vsync
(II) CHROME(0): Modeline "640x480"   25.20  640 656 752 800  480 490 492
525 -hsync -vsync
(II) CHROME(0): Modeline "720x400"   28.32  720 738 846 900  400 412 414
449 -hsync +vsync
(II) CHROME(0): Modeline "1024x768"   65.00  1024 1048 1184 1344  768 771
777 806 -hsync -vsync
(II) CHROME(0): Modeline "640x480"   23.75  640 664 720 800  480 483 487
500 -hsync +vsync
(II) CHROME(0): Modeline "800x600"   38.25  800 832 912 1024  600 603 607
624 -hsync +vsync
(II) CHROME(0): Modeline "1024x768"   63.50  1024 1072 1176 1328  768 771
775 798 -hsync +vsync
(II) CHROME(0): Modeline "1360x768"   85.50  1360 1424 1536 1792  768 771
777 795 +hsync +vsync
(II) CHROME(0): Modeline "1280x768"   79.50  1280 1344 1472 1664  768 771
778 798 +hsync -vsync

which shows that the TV provides a 1360x768 modeline, and

GetModeLine - scrn: 0 clock: 85500
GetModeLine - hdsp: 1360 hbeg: 1424 hend: 1536 httl: 1792
              vdsp: 768 vbeg: 771 vend: 777 vttl: 795 flags: 5
GetModeLine - scrn: 0 clock: 85500
GetModeLine - hdsp: 1360 hbeg: 1424 hend: 1536 httl: 1792
              vdsp: 768 vbeg: 771 vend: 777 vttl: 795 flags: 5

Which shows you are running with that modeline

I think your problem might be with this section

All of your modes are 60Hz (NTSC) and not 50Hz (PAL).

I think you need to try and dig up a 50Hz mode to put in your xorg.conf
and test with.
