i paid for and downloaded a perfectly good 1080p music video with karaoke words and dual audio. one track with the singing and one track with just the music. the problem is that my karaoke machine wont play 1080p. so all i want to do is down size this to 720x480. sounds like the simplest thing to do but i spent about 4 hours now trying and no go. it needs to be in mpg format. when i use sony vegas pro, after i render and output it, there is only 1 audio track. how do i keep both audio track and just lower the resolution? i tried virtual dub, tmpgenc, handbrake, super. but nothing works. i did some googling and found some articles about dual audio as in left audio and right audio. this is not the case. if you go on VLC, and goto audio tracks, there is cleary a track 1 and a track 2. after i try to down size it using sony vegas, there is only 1 track to select.

Extract/convert the audio from your original video with for example Pazera Free Audio Extractor. Convert to mpa(mpeg1 layer2) or ac3 audio and it should work best in a mpg file.
In tmpgenc(file->video tools->multiplexing) or ImagoMPEG-Muxer can you then try add a secondary audio track to your current mpg file.
that worked perfectly!! thank you. it was quick and easy to follow.
And it worked in the karaoke machine?
yep. worked perfectly. thank you.
