i have a couple dvd copying questions. i figured id post them here since i like the scene so much

whats the difference between DVD-R DL and +R DL and which one should i use?

i got a pack of +R's because thats all they had at the store but the movie i copied with DVD Decrypter didn't work in my xbox or dvd player. but it seemed to work fine in my computer. it always seemed like DVD -R's (non DL) worked better than +R but i havent done much with either.

also, should i use DVD decrypter to copy the iso on to a blank disk or my usual burning program. my roxio didnt want to do it but its pretty old i think i need to upgrade.

and can anybody recommend a good dual layer dvd burner that supports all formats. or should i wait until i can get an HD DVD burner before i worry abouit. right now im using my dads burner thats why i ask.

thanks guys

nevermind, i found doom9. still any recommendations on a dual layer all format burner. or should i wait for an hd and blu ray burner?
