Re-encode Audio Track

Sometimes, we may have issue in playing audio part of video with some players or media devices, though the video format is listed in supported media part. Why is there such a problem? Generally , a video format/extension may contain one video track and several audio tracks. There may be several codecs, one for each track. Most TV, portable media devices don't support FLAC, DTS or even AAC and the above audio codecs are often used in MKV, AVI, MP4, etc. So when you have such issues, converting the audio track to compatible codec for your player is the best solution.

Some Video Converters support audio codec settings and you can choose widely supported codec like MP3, AC3. However, most time, the video part will be re-converted too and it cost too muck time and we will loss the video quality. Is there any converter which can change audio codec directly and easily?
