Problem Recording Audio From Reason 3 To Dp 4.6, problems recording audio with mac mini Options

[mexxxican]

hey people wondering if i could get some advice. im having problems recording audio from reason 3 into DP4.6. i´m using a mac mini 1.25 with 1gig ram. i am only using say 10 synths at a time max and i normally just record a stereo mix into DP4.6 the problem is that when i record into DP the audio sounds crackly like digital at times and seems to momenterally cut out. when there are long synth sections they seem to stumble and dont sound fluid. i´ve tried messing around with my setting (buffer size etc) but am still having some problems any help would be much appreciated
