Advertisements There are some odd Sonic filters I don't have on any of my 4 machines. By any chance did you have earlier versions of MyDVD or DvdIt on your machine prior to loading the latest? (could be that it was installed automatically as a DVD burner bundle). Check the control panel applications install/ uninstall. First unreg the sonic scaler and have a go. I don't have that one. (I have the 9x8 filter, but not the Roxio filter.) If that does nothing, leave it unreg'd and read on. My graph path is identical except for the Sonic splitter. As I said, I don't have the sonic splitter on any of the machines that work. So, without a clue why a splitter would screw up a known good decoder, just because it is simple, how about trying Unreg'ing that one. Be sure and save all unreg command lines in a file as I warned. It makes it easy to undo stuff later. After unreging, redrop the .tivo and see what it comes up with. See if there is any affect on MyDVD by restarting it. In graphedit, what I see in my graphs is just like yours, except "MPEG-2 Splitter" in place of the sonic one. This is a generic demuxer from MS. You need to keep unreging (or setting the priority lower) on the splitter/demuxers that occupy that slot until you get this one in this position. It is standard with XP, so you should have it. I also don't have the Sonic Mpeg decoder. On most of my machines, the only things I see with Sonic all say sonic cinemaster, except one that says Sonic DVD-VR navigator. So if you are still hosed on the scaler, unreg everything Sonic that doesn't fit that description. Then give it a go. By this point, if it is not working, you may be reminded of the Boys in the hall skit with the husband washing the temperamental car in order to persuade the engine to turn over. At this point my car washing opinion would be that there are other filters that are interfering downstream of the decoder. Known trouble filters are from Nero. Try temporarily unreging all of those without consideration of what their names are. Sonic acquired Roxio so on the off chance that they give any preference to Roxio filters, unreg those too. It is a hell of a pain, but if you keep accurate notes, you can send them into Sonic support and post them here and either they can fix it, or at least have accurate information to troubleshoot users in the same boat. Let me know what you find out. This is an interesting problem.
