Made a few changes.
I updated to a newer kernel, trying to get usb working, but apparently it's still not there yet.
I overclocked to 710 Mhz, seems stable and a bit faster, not sure if it's worth it or not.
This
post explains how to add some additional codecs. Now I can play all the movies and videos I already have, but I still have problems with some HQ YouTube vids.
David, have you looked at
CyanongenMod? What do you think of it?
