Hello
I use Video DownloadHelper with Mozilla to download videos from youtube. I had already installed K-lite full codecs. The problem is that mp4 and flv files from youtube I only see the video but no sound. With MediaInfo software I noticed that those mp4 and flv files have no information about the audio codec, only video codec, for instances:

No audio information at all. How can I solve this problem?
Best regards
