I'm having lots of problems with 2008/1 and v31 not seen with previous versions. I've customised the DVD to include full UK post codes and v31 to include my own splash screen and a few other minor navtweak changes (same changes that I've made since v27)

Issues:

v31 seems much slower to start-up and to read the nav disk. Changes to scale take about twice as long as before to redraw the screen maps. A directed journey sometimes crashes - the maps continue to be drawn correctly as is the position of the car but the direction instructions (visual and spoken) and the ETA etc are all lost. Reboot via ignition solves this.

I suspect there may be issues reading single layer DVD's (we know v31 includes dual layer support) but could be anything I suppose.
Cleaning the DVD or reverting to an older 2007 version (all backup copies) makes no difference.

Anyone have v32 yet?
