Advertisements Hello, I've all of a sudden been having issues pushing certain mkv files to my tivo's. All has been great up until recently and it is only a select few of the mkv files I have (Most transfer perfectly fine). The problem mkv's all appear to be AC3 audio but they don't play properly in Windows Media Player either. The Video is fine, but the audio makes a flickering noise from start to end. The same files plays fine in VLC and Windows Media Center, but will only push a portion to the tivo. It appears that I can pull it to the tivo just fine as well, but I want to push it to a specific folder. I've updated to the latest version of pytivo, checked and have 1.02 ffmpeg, and don't really know what else to look for. Please help, thanks in advance.
