I have had a Sony DVP-CX995V DVD player for about 5 years now. A couple of years ago I made the mistake of downloading and installing an update. Since that time, and after re-downloading the update and multiple attempts at re-installing it, the remote control has ceased to operate the unit. The supplied remote no longer controls it and it also does not respond to any universal remotes. I contacted Sony probably 3-4 times regarding this issue, the last time a lady said I would get an update disc in the mail. This had been more than six months ago. What gives??
