I have 2 older DVD readers that will not read a DVD-RW which I made in Nero with UDF 1.02 ISO, my burner can read this, but not my 2 readers. It is a single directory with 1292 zip archives.

Is there a list of readers that read "ALL" formats, or some formats?
Or is there a method of flashing that can "make" an older DVD reader work with the various formats now available?

DVD burner: Plextor PX-708A
DVD reader: Toshiba SD-M1402 Firmware: 1012
DVD reader: Toshiba SD-M1202 Firmware: 1028


I have flashed the 2 DVD readers several months ago, and the current firmwares for both of these readers are the same at "The firmware forum"
Thanks for reading this,
Jon
