I took a look at your samples and have some suggestions and apologize for overlooking them when posting my previous reply. First off, as it's already been said, since your source is soft telecine you SHOULD be using force film. To really figure out what's going on, running ignore pulldown flags will give you the raw video (NOT RECOMMENDED FOR REGULAR ENCODING!), and based on the clips you uploaded those combing artifacts are in the raw video. Feel free to use check one of the full episodes with this method to see if there are any leftover interlaced frames in the footage, however I get the feeling those artifacts were a result of the footage originally being interlaced, then inverse telecined improperly before being encoded for DVD. As I stated before, the condition of your clips are the exact same as the hard interlaced version on the release I have (same frames have the exact same combing artifacts).
Also, as Mister Hatt mentioned, you should probably be using the latest version of
DMPGDec.
