It doesn't seem like a security issue to me.
Popular software packages have tendencies to "take over" your OS, even the little things like autoplay when it comes to PowerDVD, ISO images when it comes to Nero, portable devices for iTunes, general playback with Real Player... It's nothing new, at least not to me. Having "too many" multimedia applications creates a mess with file associations if the particular software package isn't set up correctly and/or completely.
In your case, PowerDVD simply added a startup service that doesn't regularly show anywhere else but msconfig; it's the most powerful tool for integrating an app with the operating system and the way it behaves when it comes to user usage, and many software packages are doing it.
