The 330 doesn't output a progressive signal at all its interlace only. The AE100 will convert the output itself to progressive scan internally but this isn't quite as good as the dvd player itself doing it. I've used a 330 on my AE100 myself and the results are just about ok. A proper progressive scan player even quite a cheap one will probably do a better job.
If you want a good quality high performance progressive scan dvd player to go with your AE100 something like this will do you proud;

It also features a full dd/dts/dvd audio decoder. It doesn't have RGB scart output but that doesn't matter if its for a AE100.
