Windows Media player 11.0

Does anyone use MP 11.0? I burned some 700 MB CDs with MP 10.0 and they worked fine, but trying to make the same CDs with MP 11.0, it says one or two tracks have to go on the next CD. I thought they both used the Red Book with that daft 2 seconds of silence between each track, so why does MP 11.0 waste extra space?

I checked with Roxio and the tracks fitted a 700 MB CD using track-at-once, and they also fitted using disk-at-once, but with the extra time for all those unwasted 2 second intervals.
