Technical, I've checked EBCD v0.5 and .gz archive is scanned, look at the results:
extracted to memory:
C:\zz\Debug\...\ebcdpro.zip\ebcdpro\CDROM-PRO\BOOT\boot.gz\boot - is OK
C:\zz\Debug\...\ebcdpro.zip\ebcdpro\CDROM-PRO\BOOT\boot.gz - is OK
extracted directly to disc:
C:\zz\Debug\...\ebcdpro.zip\ebcdpro\CDROM-PRO\BOOT\boot.gz\unp30512 - is OK
C:\zz\Debug\...\ebcdpro.zip\ebcdpro\CDROM-PRO\BOOT\boot.gz - is OK
Igor wrote, the content is not scanned. The .gz archive has the only one image file which was really scanned.
I've installed .br version of RealOnePlayer but I didn't find any WACHBJRB.zip file in the installation folder. I've sent you my ftp connection details, you can send me the file.
