<html> <head> <style></style> </head> <body class='hmmessage'> Hi Guys All the advice is very much appreciated, and the views expressed about the merits of different audio formats and players are of great interest too. Like everyone else on this forum, I'm not happy about resorting to a Microsoft audio format. However, when funds are tight, upgrading players isn't an immediate option. My only format options at the moment are WMA and MP3. Which format sounds best is, I believe, somewhat subjective. All I can give is my own experience using the equipment I have available. The insertion of "-acodec wmav2" into the ffmpeg command line has done the trick. Many thanks to those who suggested it. Regards Nige </body> </html>
