Another suggestion besides d-pad or a different volume control app would be to just use the touchscreen when you're on the volume control page. You can touch at any level to adjust the volume. Now, those of us with larger fingers may need to break out the stylus to get finer adjustments, but I just tested it myself and was able to use the very tip of my thumb to get the volume down to one bar.

Edit: That seems to only work on the System volume tab. The ringer volume still only adjusts in 3 bar increments (which, I believe is just a limitation of WinMo's ringer volume levels but if anyone knows different pls correct me if i'm wrong)
