I tried get Firefly to serve the resulting TS (video transport stream) file to iTunes and was rather surprised to find out that it had a go at transcoding.
you might want to try the software here: http://www.squared5.com/ if there’s no firefly/server side solution. I use mpeg streamclip for tv progs recorded to my PVR which I then want to rip to a computer compatible format. TS is supported as you’ll see on the squared5 front page and I think it should work for straight audio files.
hope that helps, andy
if you can find a program that will take a ts file and turn it into a .wav file, then you can make it transcode. I don’t know one of the top of my head, as I don’t have any .ts files, but I’d be interested in hearing if you find one.
