Bumblebee- Are you remuxing or authoring? If you're remuxing, are you saving all the extras? If not, then authoring will probably solve your problem. If you're remuxing, which version of IFOEdit are you using? Try using v .6. If your m2v file looks good, then the problem probably isn't ReMpeg2. If you've got loops, maybe you have angle issues or seamless issues you need to resolve first. Good Luck!
