I have pre transcoded a movie and it appears to have worked but I'm not sure how. I started pretranscoding and after a few minutes I played the movie on my TV and it worked until the playing "caught up" with the pretranscoding and then it stopped or stuttered. I left it for an extended period and then tried again and it was OK. So how do I know when the pretranscoding has finished. There is no progress bar etc. Any help please?
