Help with ACARD 2032

Hello,

I recently purchased an ACARD 2032 Unit for 1-7 copying stuff.

In the Tower… i have 6 Samsung 52x burners. (CD-Master 52E Model Sh-152)

When i go to Device Info, the ACARD recognizes the cards as SAMSUNGS and tells me firmware and all the info… but when it comes to burn time… it wont burn em… i have ONE
LG 52X burner… model GCE-8526B) and this is the only dive that burns… is there something im doing wrong? My burners have to be compatible cuz the ACARD recognizes them… right…?

dont all your burners have to be the same? and preferably the same firmware 6 samsungs and a lg will def give you problems
