Hi, Sorry for not posting for a long time, my computer was actually having some very big problems. Anyways, I have two AVI files, I wanna join them together but the audio data is different. If I load them both directly into TMPGEnc and convert to MPEG2 the quality doesn't turn out good. Is there something I can do to the audio in the video so they both have the same bitrate I think. I tried using TMPGEnc to convert AVI to AVI, a few days back it gave me a couple of audio codecs to choose from now it's giving me none to choose from. Any different ways of solving this problem so either to get TMPGEnc working or join the two avi files a different way? By the ways, I am using TMPGEnc Xpress. Regards, DiRect
