I uninstalled the last version of Cyberlink's Power DVD. Obviously, the "patch" from ntfs.org did not uninstall. Now running v5.0, and, well, my spdif is horrendous! Stuttery and all. Tried 6 spk setting and although the stuttering was gone, so was the dd and dts. Is it possible that this patch, interfere's with the new verison?
