Can anyone tell me if there is a difference in the DivX and MPEG4(part 10) codecs ? I have been using the Mainconcept MPEG encoder to convert AVI to MPEG2 and that works fine except for DVD quality on long movies to a single DVD. The Mainconcept MPEG4 encoder is due out in the spring and it would seem smart to use the newer codec for conversions. In looking at DivX players, they all seem to show DivX and MPEG4 as being the same family ? If a player plays DivX, it plays MPEG4. As I am really satisfied with the quality of the Mainconcept product, I expect that their new encoder would continue to be of high quality. Waiting a couple of months to get higher quality conversions at lower bit rates makes sense if, in fact there will be no player compatibility problems. I realize that neither Divx nor Mpeg4 will play on older players. Thanks for any info.
