Okay now I understand what your trying to do, DVD to SVCD with DVDx and CCE pluggin. If it has been working and now it does not, I suspect you have installed some other software that is interfearing with it. Or have upgradded something or both.
To be honest, DVDx is not the way to go for SVCD. A much better and simpler solution is the all in one program DVD2SVCD that uses CCE as full program and not as a plugin. Absolute supurb results and all explained in the Movies Tutorial section.
As for VCD, the quality from CCE is quite poor compared to TMPGEnc, just to much pixelation in fast action scenes. The latest DVD2SVCD can now make VCD's with TMPGEnc however they end up not fully VCD compliant, so go with the proven DVD2AVI / TMPGEnc method. Its one of the fastest and best quality, again read all in the Movie Tutorial section.
