I have a Lite-0n SOHW-1693S with the KS0B firmware installed(today) and i noticed that it's been reading my DVD+R discs as only having 4.483gb of space.  I was using TDK DVD+R x8 media and it read up to ~4.6gb of space.  Yesterday I bought some Memorex DVD+R x16 discs on sale and now this is happening even for the TDK media.  Does anyone have an idea why this might be.  I've heard of people reseting their drives somehow so that it relearns media but I don't know how to do this.  Thanks for any information.
