when i got my 1620 a couple of months ago, i flashed it with the b7t9 cvt and the RPC1 hack. then i used the mediaspeed patch. now if i want to update my firmware to say b7v9 do i have to redo the RPC1 and mediaspeed patch as well. what happens if i just update the firmware from benq's website, would that rid the drive of its ripspeed and region-free hack. or would it be best to use windwflash with the b7v9RPC1 from http://dvdpro.club.st/firmware/BENQ_FW.htm and then use alas mediaspeed patch tool again with the b7v9RPC1 exe that i got from dvdpro. anybody can confirm the steps to update firmware once you used mediaspeed and regionfree hack before. thanks.
