ADSTECH unit...DVDEXPRESS DX2 model...uses USB port to capture video signal. I am able to convert old VHS tapes to DVD....problem is the sound. I have good video, but no sound only on some DVD players. Converting old family VHS tapes to DVD to pass along to family members. I have an APEX DVD player and both video and sound play ok...but Phillips dvd player will play video but NO SOUND. Both units play a -R type format....the program called CAPWIZ is used to capture the video from the VHS tape to the computer..is there some sound setting that I can make that will make these conversion, that will make these play video and audio in ALL DVD PLAYERS?
