Sensei: In general, from what I've seen, if there were conflicts, you'd know without a doubt.
If things seem to be working fine, don't touch a thing. If only one or two programs are giving errors, I'd recommend starting a new thread concerning the errors (as they may not be video related at all, unless you can tell). If everything's throwing crap out errors at you, windows looks funky at best, etc., then you might have conflicts. At that point, come back here with the symptoms, and we'll give a try at helping you with em.
