I have Ulead VideoStudio 7.0 and when I open (add) VCD mpeg-1 video clips that I've made with TMPGEnc, there's no sound with them! But there IS audio when I open them in WMplayer, for example. Other files have sound, just these which I made with TMPGEnc don't. Why? It seems that it doesn't recognize the audio format. How's that possible? It's mpeg-1 for god's sake!

Thanks for your suggestions!
