Exactly, the problem here is not about technical things, but rejection of DSE as a defect by Philips. It is rediculos , but after last reply from the company they sent me email with request to fill in a feedback form about TV that they could publish on site. I provided it and mostly wrote about DSE and how Philips consider it. I believe they already have enough positive marks from other users, that is why my reply was 90% negative. It is easy to guess that my review was not published with note that I'd violated some points of Instruction. They also kindly provided a link to Instruction, but it does not work with 404 error. What I could expect if I didn't glorify Philips? Very sad experience...
