Can anybody help. I've just installed windows 7 and I am trying to convert wtv file recorded in media centre to dvr-ms file. The first time I did this it worked perfectly fine. However, since then the program seems to have stop working? The program starts converting the file then after a while the program stops. Has anyone else used this program and if so have they had any problems? At the moment there seems to be little information about what could be causing the problem. If anyone has any ideas I wouls be grateful to know.
