I remember asking this on the "old" forum and nobody had a straight answer. Can the DVD drives on the 770s mount/load DVD +/- R(W)s?
On some strange whim this morning, I stuck a burned (DVD+R) movie I made a while back in and the thing actually worked!

I hadn't thought to try before as all the data DVD +/-R's I had wouldn't mount or were considered "unrecognizable" by my 770X. It seems like the drive can actually "see" the formulation of the disc (since the movie did work), but for whatever reason doesn't recognize the file system on data discs.
Anyone have any luck getting data +/- R(W)s to work?
