I've been using CCE SP 2.7 for quite some time now, and Ive been quite pleased with the results of my dvd rips. I normally just rip full dvds (sometimes with or without extras), and remove all the trailers, some audio streams, subtitles etc. with dvdremake pro and shrink.
My average compressions are anywhere from 60% and up depending on the length of the movie (have had one with 50% compression also).
Now theres been alot of controversy between CCE SP and Procoder, and everyone has had their own inquiries. From some of the results I have seen with comparisons, at mid to high bitrate levels at 3000-5000 kbps, they look very similar... each have their own unique qualities and sometimes setbacks also.
With lower bitrate levels, I have noticed that Procoder is better at keeping the image sharper, but I havent really run into any problems yet with my bitrate levels and CCE SP as they have never gone under 3000 kbps.
Time is of no concern to me as I just want to produce the best possible backup possible, but if the difference are going to be minimal at such bitrate levels where the naked eye can barely tell a difference (btw, all my movies play on a 37'' sharp lcd tv), then I'd rather just keep CCE SP. But If there will be marginal differences, then I will start to use Procoder 3.
I've seen the huge differences between encoders like CCE, Procoder, TMPGENC and HC blowing DVD Shrink and CLonedvd out of the water....but encoder wise, they all produce relatively beautiful compressions.
Is it worth it to dish out the 500$ for Procoder or should i just stick with CCE SP?
