It is displaying proper statements but it is neither recording nor playing…Only tic tic sound is coming for a very short periodx
I am able to play S-Video too but Audio dosent work. I tried to copy and play the file on Linux PC also but the same problem i.e; no Audio Output.
What is the 1st step Make sure whether your player is running or not?
