During my trial, I found Corel responded to editing with a tad of delay after clicking on it's options. But it's stable, no crash.
It's resource friendly too - while Corel record the video and audio (via the webcam mic), I can record properly into X2 with proper mic / instrument line in - so I can further do mixing.
I'll edit the video in Corel later and replace the webcam audio with the proper X2 mix - with the help of wave form shape to align the audio in place before removing the webcam mic audio. I can further repeat this for video in video editing too - I won't get pin point accuracy, but the hand alignment is good enough - no noticeable out of sync.
Is the the correct way to do video-in-video editing ? (beginning to sound like this should go to Technique forum already..)
