OK I'm not exactly sher what this is. i was using avi2dvd and everything was going great...until i had a friend email me an old movie he had on his computer (Seven Samaria) i had no problem fusing the two files together for one DVD. And the audio went fine from what i could tell. The real problem was when it tried to author it i think. The HCenc told me there was an Invalid MPEG2 file rate? What is this and how do i fix this is my question. Do i not have the right codecs, or is it something else? here's the log from the avi2dvd [11:51:13 PM] AVI2DVD Started !
