I use the Sample Magic / Loopmasters stuff a lot as well. Not sure where I got it... but it has one shots that are kinda cool. 

You can drag'n'drop the audio from a drum replacer region FX to a midi track. There, you can feed it into any midi instrument like addictive drums.

I clipped a sample from Aerosmiths "Walk this way".
I sliced up the intro used the kick, snare, Hi hats and had myself a simple but yet fat sounding kit to use for stacking.
many possibilities using DR. I keep meaning to make a video using some of my trusted methods.

Ty chuck thats exactly what i was going to do using "shes so selfish" by the knack....ty scook and john joseph as well and all the other great comments...gonna make a mean kick i hope

This is good to know as I gave up on drum replacer because the included sounds to me were all wrong for my needs. 
I have sampled my own drum kit and use Session drummer to play them. So what is said here is I could also play them in Drum replacer. However I  like the idea of just creating a midi track and using a proper drum synth because of the mixing options available. 
I have lots of recordings that use real drums that I'd like to enhance. I tried dragging an audio Snare track to a midi track and Melodyne put it in 20 different midi note values. I was going to look into this too as I think there must be a way to change a setting like we used to do with Audio Snap and assign one note.

I am a huge knack fan. Love that song as well.
Really upset I never got to see them before Doug passed.

Me too.. I actually talked with him(doug) briefly via email before he died...i also think berton is one of the most underated rock guitarists of all time...his solo on my shharona is orgasmic in my opinion..not the stupid edited for time version which pisses me off every time i hear it...how could they cut such an awsome solo

If you want to capture audio from a cd or external audio or even streaming audio you can use audacity which is free.
There is info out there on how to set it up to do this. From there just save the audio and drop it into Sonar. Once there you can chop it and drop it.
