LDW-811s & Ultra Speed Verbatim CD-RW

Hi,

Last week I have bought a LDW 811S DVD Burner. Yesterday I have tested burning Verbatim CD-RW on 24 speed. It burns fine at that speed. There is only one problem the CD-RW is difficult to read in an other drive. I have used the latest firmware but it didn’t work. Is this a bug in the firmware ?

Regards,

John
