I'm also a maccie, would be nice from you to explain what tools you use to improve the image of non-anamorphic DVDs, especially when there is no tool like AVIsynth.
For encoding I normally use MainConcept Encoder (I think the resizer is superior to compressor), and it's much faster also.
But what to use for "improving" the image?
