Ok, so I gave in about a year ago and a half ago and bought an HD DVD player. DOH!!

That's me waving like a doofus.
I thought that since Sony seems to lose out on all things they try to make commercial and propietary (BetaMax, Mini Disc, etc), I thought it was a safe bet that HD would win over Blu Ray merely because Microsoft and Toshiba backed it and it was more affordable. Boy was I wrong! Anyone else make this mistake? I now have a $399 player and about 35-40 HD movies that are in essence, worthless. I tried to sell them locally, and I was denied. I paid upwards of $30 a disc or more in some cases, and want to at least re-coup some of my dough I spent. Anyone gone through this?
No, I am still not buying Blu Ray (at least not until it comes down in price)
