Audio problems

[qanda]This thread is about the Sony DVD Player. Click here to see full specs[/qanda]I have a DVP S7700 player. I burned a video ts file to dvd. It plays fine on the computer. I used a sony DRU 810a burner. For some reason it plays audio during the menu but when I playan episode in any fashion ie auto play , individual episode or by chapter there is no audio at all. I have tried this in another sony dvd player as well with the same results. I ran it through gspot codec tool from kliter and all shows up as AC3.
Any suggestions:bow:
