I have beena transcode user for quite a while now - I tend to use an editing oftware followed by transcode to convert into mp4 or more specifically xvid.
I buitl a new system, and am using the onboard audio, and since I did this I am finding videos which are recorded from software such as Keffeine or mythtv are playing back fione in the application they were recorded in, but when I try using avidemux or other editing software in ubuntu, or even boot into windows and try editing there, I am straightaway seeing a sync issue in audio and video. I am jnot sure how to get round this, and obviously transcoding is not even an option - I know I can delay or advance audio, but I would like to correct whatever is happening, and anyway even if I simply tried to adapt everything to resync, I am not convinced I will get a good result. The system I have is an AMD Dual core running ubuntu 7.1 with gnome 2.2. It has 2gb rom, NVidia GE force 7 graphics Gammagraphx GeForce 7600 GT, audio is Giga-byte MCP55 High Definition Audio
