89.893 pounds='bout 161 dollars.
DVD-R is the one that I see listed as being about the "most" compatable with set top or stand alone DVD players.
It has been around about the longest I think as well.
Most cheapy players won't, or have a hard time playing burned discs, but if you look at the specs on a lot of the new players, they say they are compatable with DVD-R discs under "certain conditions".
I think this means some players might not like brand "X" media, but will play fine with brand "Z".
What's the PITA though, is they never say which brand seems to work best. I guess it's left to the end user to figure out what brand of media their particular player likes.
hope this helps..
