So i have an 18G mpg file that i want to combine with a 22MB SMI file, and then be able to edit and cut clips out of it. Im using VirtualDub but it freezes due to the large size of the SMI file. I downloaded VLC and it allows me to play the video clip with the SMI subtitles but it does not allow me to edit the video.

Anyone has any idea on how to change the settings in virtualdub to allow the large SMI or know of any other program that will edit these 2 large files together?

any help would be greatly appreciated
