How to convert drm audio and video?

[Lotion]

I'm trying for a while to convert protected wmv to mp4, all the methods I've tried failed or didn't like quality of the converted files.
I would like to put my videos on my iPhone and I need to convert them as those files are drm-ed. What drm converter do you use? I need a good one which doesn't affect the quality of the files.
Thanks

For me MelodyCan is the best software for different players. It can remove drm and convert files to different formats. You can try it_))

Two first time posters? Whats up with the spammers asking questions about conversion and PS3 and Xbox stuff on here?

I think if you Google "Best place on the internet to find answers to random ****" Cyclone Fanatic comes up as the first match.
