Is it really compatible with the PS3?This seems to be an excellent chair; very easy to assemble and perfect for our 9 year old boy and his friends. The only very huge problem is that we cannot get it to work with his PS3. Upon ordering, I chatted with customer service who contacted Repose to find if it was compatible. The response was yes. We received the chairs and the cables did not work with his game system. We called Repose; they are testing on an older version of the game system, which does not use HDMI cables. They advised me to purchase different cables and run it through our TV; which is also new. We did the same, and still cannot get it to work. I am so dissapointed, especially since the rep called Repose to verify that it was compatible. Maybe they should update their test equipment.
