I just started using Avidemux and so far I have found it to be a great program. However, I am having an issue when I try to open a .flv file to cut. Avidemux only loads a small portion of it (00:01:43:266). The actual video size is 57m 55s. I have tried uninstalling and re-installing the program, searching for similar issues and deleting the appdata. I have already cut a .flv file successfully, but I am having trouble with the second. My OS is Windows 7 64 bit and I am using version 2.6.4 Avidemux. Any help or advice is greatly appreciated.
