basically i have two avi files cd1 & cd2, I join them with virtualdub and then save the audio to wav on full process mode, I have then tried using the wav and avi in tmpgenc to encode to dvd, and get stuttering or extremely bad audio but with movie fine.
So i then try converting the audio to mp2 and get illegal audio stream error! basically ive tried this process and quite a few others on severel avi's and get the same bad audio problem.

Much appreciated if anyone can shed some light on this and help me out here, if any more ellaboration is required on this problem just let me know .........thanks in advance.
