As we commented earlier, the new TiVo Desktop 2.1 blocks the use of Dr. DivX, TMPGEnc, and some other video encoding/conversion programs. If you’re comfortable using a hexeditor, such as Hexworks, this is easily fixable — for now, anyway. All you have to do is find the DLL file:
C:Program FilesCommon FilesTiVo SharedDirectShowTiVoDirectShowFilter.dll
Open it in your hexeditor, search for the program name (e.g. “divx” or “tmpgenc”) and add a letter to the name (e.g. “divxx”). Save and quit the program. By changing the name of the filtered video conversion program, you disable TiVo Desktop’s ability to find and disable it.
