I was browsing through the DVD contents and noticed that the home sounds (dog bark, bell, church etc) are simple WAV files. Anyone add there own clips? I am sure it can be done, but the feature is pretty annoying because it repeats too many times. !

You would have to rip the disk image to your computer, replace the default WAV files with new WAV files bearing the same file names as the old ones, then burn the disk image onto a disk. Not really that hard of a job. Pretty much the same way you do custom backgrounds on the older units.

You just have to remember which custom sounds replaced which default sounds.
