Two issues

1. While importing a .mts file audio and video getting unsynced(they are not together ,while moving both act independent). This was never a problem when i used this on Windows7.I recently upgraded to Windows10
2. While trying to sync two video channels and an audio channel, by selecting all three then right clicking ,Group-Creat new-- i can do it but they are nor getting grouped any more. When i make a cut the the only highlighted channel is getting cut, not all three

I never had any issues with above two steps in window 7

Please help
