I've been using Vegas with Windows 10 for more than a year without a problem. But now, I built a new PC and did a fresh install of Win 10 and Vegas 11 Pro and I have an issue with importing media files.. Both mts and mpeg2 files result in green screens in Vegas. Both with and without GPU turned on. However, mov files work fine. Apparently I'm missing some codec's but I don't know where to get them other than downloading one of those codec packs that I really don't trust. Any suggestions?
