I have been using Nero 6 Ultra Edition for quite awhile now. I've used Nero wave editor to edit mp3s. I've also used VisionExpress to burn many dvds. Just a few days ago when I tried to open wave editor my computer starting prompting me to install Easy DVD/CD creator 6 (which I already have installed). I thought that was very strange so I just canceled out and left it alone. It happens everytime I try to open this program and for some reason whenever this happens I can't use Media Player Classic to watch avi files. I get an error message instead. If I restart my computer MPC will go back to working just fine. The second problem with Nero is burning video. Like I said earlier, I have been using the Vision Express software for quite a while now, but ever since the above incident started my dvds are not burning correctly. Some discs are coming out as unknown disc and my computer stalls out just trying to read them. A recent disc burned but it looked horrible. It looked like the compression rate was set way to high and the bottom of the screen is kinda stretched out looking. Is there anyone out there who can tell me what the hell happened?
