I just got a new Sony DVD burner and with it came " Nero StartSmart Essentials "ver.7. When I first tried it on MPG movies it worked fine. But any time I try and add an AVI file it freezes up.Any help would be appreciated.. It worked great for the mpg's.. Being a newbee it was nice that it worked the first time with these files, but over half of what I have are AVI's..
