Have a Pioneer dvr-104 with latest firmware updates downloaded. Running Windows XP Home Edition with 80gb harddrive. Pioneer will read and write dvd r just fine, does not recognize dvd rw, just keeps telling me to insert disc. Microsoft website says that dvd rw use a 16bit packet, as opposed to 32bit pactet for dvdr. Can anyone tell me how to (change setting, install this 16 bit packet, or anything else) that will let my machine read and write dvdrw? Thx for any help
