hi,

i have a pioneer dvr-104 dvd writer with the 1.30 firmware, but im thinking of upgrading to 1.40 from the pioneer site, but before i do, can anybody tell their experiences, any hickups they might have had in doing the upgrade, or any comments really,

Also will the upgrade affect the reading of previous DVD-RW's which i have burned with 1.30 firmware,

thanks
