It doesn't matter what the marketing department or whoever at Real Player says. You can't convert video to audio. They are wrong and misleading.
Bass Thumper's original wording was about "converting the video file to an MP3 file".
Note the use of the word file.
What Mike initially wrote was "convert a video file to MP3" then later "convert video to mp3".
The
file conversion from YouTube video to mp3 audio is not a lossless process ... it will, of course, lose/discard the video part, but the
file is converted.
I agree wholeheartedly about the "Newton Meters and Pound Feet" observation, but I also note that the same damage can be done by reinterpreting the text into something it never was.
