renshaw8,
I'm not sure that the problems are coming to you from "RealPlayer 10". I have it installed on my PC and I like it.
I had before, the precedent version of Real. It didn't work correctly, and it caused some troubles to me. Now, I'm very happy to have this new version of Real 10. But the difference between me and you is that my system is XP. Anyway, probably you have to search the cause of the problem somewhere else. Or, try to uninstall RealPlayer and restart your PC, then reinstall it again.
I'll add and confirm what Sandra told. That I didn't hear about MP2. That file type doesn't exist in RealPlayer 10.
Sandra, I didn't have any adds because of this program. While installing it, you need of course not to accept their adds. For me, it's a good program. Add to that, that some internet sites need this program to be used for their specific files.
