Settle pettle :bigsmile:
So trying to play the newly created vob files does not produce any sound on the PC ? First of all what program are you using to play the IFO/VOB files with ?
Also, is the audio in AC3 or MP2 form. If AC-3 what program did you use to convert them with? The latest BeSweet produces an AC3 file with no sound so either use and earlier version (not sure on the number where it works) or try the new TMPGEnc AC-3 Pluggin. It can be run standalone and can convert the WAV to AC-3 no probs. Or try Soft SoftEncode if its still available. If you have Sonic Scenarist, there is AC3Enc included in that package as well.
If the audio is MP2, then I suggest your Windows installation is screwed.
