832 firmware MAY possibly improve poor media burning results in some cases. It will improve good media results. I would recommend staying away from poor media, as it seems to cause a lot of problems and unneccessary headaches.
To flash to an 832, you do not need to flash your eeprom, only flash your firmware, but you should back up your eeprom first. Download OmniPatcher. Then download 'CG3E' from under the 832 here and select 'CG3E' from under the 'LiteOn SOHW-832S' heading. Go here and follow cross-flashing instruction method 1. In OmniPatcher(method 1, step 3), select "Apply recommended DVD...", and "Increase dvd..."' and " Enable auto=bitsetting", and "fix the 'dead...cross-flashing"(if that isn't greyed out). Save the file. Then run the file(its an .exe file). Make sure you select the correct drive....restart and rejoice!
