2 questions,

1- i converted 3 svcd's into quick dvd's, only 1 of the 3 worked on my dvd player. what could cause this problem??

2- whenever i've backed up a dvd in my collection to a dvd folder, i could burn the Video-ts folder fine with dvd clone. but after i convert an svcd with this svcd2dvd, the only app that seems to be able to burn it is a new compilation in nero.. not even the nero program that comes with svcd2dvd can seem to handle it. i get an error.
is svcd2dvd converting vcd's to a true dvd format that can be read in all players or what?? plz help... sorry if my question is vague
