Starving

Hello, So I want to use Video Pad as a replacement for Windows Movie Maker, since it is no longer supported, and I feel this program is more responsive anyway. However there is a problem I am having. I can record Live OTA TV, and the recordings are in the .wtv file extension. Now I want to use Video Pad to cut the commercials out of my TV shows, but sometimes the TV signal gets interrupted slightly, and that throws the audio out of sync. When the file is still in the .wtv format, the audio fixes itself, but even when I'm in the middle of editing it, it won't do that any more. So my question is, is there some way I can export the video to a format that most computers can read(e.g. .mov, .mp4, .avi, etc.) but still keep that property where the audio self fixes? If I can't do that, then how do I get the audio back in sync while its still in the editor? Thank you in advanced to anyone who helps!
