Hey, first-time poster on the forums, but I just had to post to give a big thanks to tortured Tomato for the guide and seaofsorrow for the fix that actually worked for me. I have the k-lite codecs and MAD filter, and Fraunhofer was disabled. Originally, this did nothing to stop the stuttering. However, I unregistered MAD, re-unpacked it, put the register bat and .ax in SYSWOW64, registered it through command prompt, disabled Fraunhofer, and voila! No stuttering! :D Thank you! EDIT: I have Win 7 64-bit, btw. EDIT #2: Oh, and here's the link to seaofsorrow's post for other newcomers that this might help: 88
