I would like to know what is the best program that can allow me to convert realmedia to dvd. I am currently using winavi but it doesn't allow me to combine multiples realmedia file into one even though I am impressed with the speed though. The reason I want to know what is the best program for converting realmedia to dvd is because winavi doesn't support joining multiples .rm files to one big files and convert it to dvd. So if you can either tell me where I can download this tool called RealMedia Editor or something that can allow me to join multiples .rm files to one big file would be fine too.
