I get decimals no matter what speed I choose (i.e. 6.1x when I want > 6x). Tried three different brands with the same results.

Bug reports have > been filed on the current package. Apologies for replying to myself. Thought I'd update the situation. Found similar symptoms from other people, but nothing coming close to mine. I posted in some forums and filed bug reports on dvd+rw-tools. No response yet. Of course, it's possible there isn't an answer to give yet. I can live with that. So it goes. I looked at the dvd+rw-tools package date, and realized that it was the same package I was using when everything worked. Starting to get confused. I tried downgrading k3b to the previous version. No luck. I got close when I booted from a 2.6.9 kernel I'd compiled just after Christmas. This seemed to work. I still had 8.2x reported as the disc speed, but the movie was watchable. No coaster this time. But compiling a new 2.6.9 kernel with the old config was a bust. Here's where I stand right now: I cannot get a reliable burn of video DVDs at 8x or higher with any current kernel I have... 2.6.8, .9, or .10 If I add -speed=1 to growisofs, I get a good disc, but it only burns at a max of 4x. Results in windows are perfect @ 8x. I still need to try with a near-stock kernel, instead of one I've stripped down. Perhaps I've eliminated something that wasn't necessary before the kernel-source package was last updated, but could be vital now. Have I missed something, or is there something broken with the software that I'm just going to have to live with for now?
