Hi, My first post. I hope this is the correct forum. My first creation of mp4s have gone fine. However I have tried unsuccessfully to make an accurate mp4 of the 1969 movie 'Battle of Britain' (BluRay) after ripping first to the hard drive. But this is only because the rare subtitle translation of German into English which is completely missing on the mp4. Playing the BluRay from the disc using English is fine. I can therefore make a subtitle free mp4, but I would prefer a more accurate version. Is this a known issue with this movie? Can anyone advise ?
