How to Convert flac and mpg files on a Mac

[Wicked1]

Ok, so I have Mac The Ripper and Handbrake, but I have audio files from a friend who uses flac format and I need to convert them, I also have .mpg from my old Windows media PC but is there one program out there that will allow me to convert these files into iTunes for music and ATV for video while keeping decent quality?

Max for audio and MPEG Streamclip for video.

For FLAC I use Max and xAct.

For mpg, isnthat mpeg 1 or mpeg 2? Handbrake is good.
