I've burned DVD using windows explorer in windows Vista.
First I right clicked on DVD and choosen Burn DVD or something like this
Then I've drag and droped files wich I wanted to burn (then progres bar apeered and I waited for 8 mins)
For the end I right clicked on DVD and choosen to Colse this disc.
Everything looks fine I can see that DVD is burned (dieferent color of disc bottom side)
But when I get back home and wanted to use my files from that DVD on XP it's looks like the DVD is empty.
The same is on MAC OS X.
