I do use a few Open Source CODEC's, so it is not the 'commercial' nature, that is the problem, but the exact CODEC's, themselves. I also try to go to the source, which might be free (like Lagarith, or UT Lossless), or commercial, such as MainConcept. I am with Fuzzy (Reply 15), on ONLY installing the specific CODEC's required, when they are required. Just do a Search in this, and the CS 4 & Earlier Forums for 'FFDShow,' and read.
That is what Harm was warning about - things might be better now, but the Adobe Premiere Forums are full of horror stories, especially related to FFDShow. I hear that many CODEC packs, that do install that, and other components, do a better job with the uninstall function, but with some older versions, FFDShow could not be fully uninstalled. It can also be very tough to fully uninstall. That particular one can cause severe problems with Adobe programs. Next, many CODEC packs also load other components, besides just CODEC's. However, as the CODEC packs also rewrite the Registry, the priority of the commercial CODEC's can be altered. That is why Adobe 'hides' its installed MainConcept CODEC's, by using a non-standard naming convention. Some of those do not work, or do not work well. There are a couple of issues, with many CODEC 'packs.'įirst, most will replace good, existing commercial CODEC's with ones that are hacked, or reverse-engineered.
