Hope someone can help me out. I'm trying to upgrade the firmware on my Philips dvp630 dvd player. The instructions tell me to write both dvpxx.rom and dvpxxdv.rom files onto a blank cd-r, using the following settings: File system CD-ROM ISO level 2 Mode 1/2/XA Character set ISO 9660 Finalised, single session Write speed slow (eg 2x or 4x) I have the files and have tried to write a disc in Toast Titanium 6 under the ISO 9660 setting but the disc is not working in the dvd player (tried twice). I'm unclear about the ISO level 2 setting and the mode 1/2/XA setting as neither seem to be options in toast (ISO level 1 is there ok). Can anyone guide me through this or suggest where i might be going wrong. Thanks in advance.
