Hi- If you like to use the latest encoding methods, then you switch to VDubMod for your encoding, install the latest AviSynth 2.5.2, use the MPEG2DEC3.dll, and use the latest Decomb for your IVTC. The major benefit is a considerable increase in encoding speed. The information you'll need to make the switch, and most of the software you'll need can be found in the . You can get the latest Decomb . Order=1 means top field first. You now have to set the field order yourself, whereas before, the earlier versions of Decomb did it for you. 410b4 can still be used, though, if you prefer. For most (if not all) DVDs, Order=1. It's only when you slice up the vobs that you might find Order=0 (bottom field first). This might occur, for example, if you're encoding some anime episodes separately that might be all in one PGC (all together in one set of vobs), and you cut them up in DVD2AVI.
