OK I can tell by watching that video it's 720P. All the TV is telling you that the source resolution is 1080P. The TV then down scales it and shows it at 720p. Sorry to be the bearer of bad news.
Actually yes you can you can buy many devices that will enable older tvs to work with DLNA. A wifi blu-ray player, boxee, LG smart TV adapter, xbox, ps3 just to name a few many many more options out there.
Ummm yeah sure get mad at the guy for telling the truth. I guess he should just say that the market has never been better!!! You better buy now or be priced out forever...lol. The most important thing about sales is creditability you you fgah clearly do not have.
