I think Winrar is up to 3.8, chech out www.rarsoft.com for the latest.
This was the first thing I have burned Dual-layer as well... I had heard Verbatim was the way to go but they were sold out at my local store, so I bought the Fujis... when that didn't work I had to search out Verbatims (and luckily found them on sale). So I ended up wasting the dough on the fuji spindle, much as you you'd be wasting the money you spent on the memorexes... but when you see this version of the flick in all its glory, I think you will agree it's worth it!
