ok people. i had the same issue with phone search and address search not working with burned discs. here is what i did without rolling back to the firmware. when i burned the disc the first time i used nero. it worked for a while then stoped. today i followed the instructions posed here viewtopic.php?f=6&t=22452. this time i used the latest imgBURN software and the disc works perfectly, all functions are back to normal. hope this helps
