I have the LiteOn 5045 Protected Input Source error when recording from the TV with rabbit ears for an antenna… I want to get rid of that MacroVision copy protection. My current firmware is SN: 0132-0141-0197-B20B (100-0100). Should I use your hacked software of the same version (197RevB US) or should I go all the way to version 204 US? One time our thumbnails remained intact but they were not playing any files when selected. We lost everything. It was almost like the FAT was corrupted. Could these two problems be related? Is this a System Upgrade, Device Upgrade or both? We defrag often to maintain the integrity of the Hard Drive. Thanks.
