hello, i downloaded a svcd mpeg-2 movie, the picture was of a good standard but the sound was very distorted. eg like the recording level was set to high

the audio files reads like this:

AUDIO
mpeg1 layer 2
224 kbps 44100hz
stereo no emphasis

now i was going to encode the audio to 4800hz anyway. so i was just wondering if there is any filters that might help with the distortion?

cheers
