I use my BR800 as my interface and soundcard.
It has a much nicer card than in almost all stock computers. I often bring in files from the BR but as said above they need to be converted first with the Wave Converter.
If they are distorted files you will see the clipped wave form and you clipped it in the BR recording.
Otherwise it's probably in settings.
You describe it as skipping so possibly it's not distortion but might be buffer settings.
