I am not sure of the quality of these discs

Which brings me to another good question, what do you guys consider the best quality inexpensive media?

I got a spindle of 100 dvd-r's at www.yesbuy.net for around 95 bucks.... they seemed to be ok until I actually watched a film that took the entire disc... towards the end the video gets choppy and just dies close to 10 minutes toward the end. I'm fairly certain this behavior is because the media is crap, it happens to me fairly consistantly when making legal backup copys of movies that take the entire disk...
