Well back again. Have uninstalled my Roxio NT2 Pro using Revo as suggested but after reinstallation have same problem. After running capture "Video Wave" for a while the audio begins to echo (best description). Have used both my USB 2 and USB 3 ports. Am runnin an HP computer with windows 8.1 Pro (had same problem with 8 Pro) with 8 GB memory, a quad processor, 64 bit system. Have also had a problem with program stopping and restarting capture with no intervention on my part. Seems I have eliminated everything but my Video capture device (Roxio UB3 15E). Also after reinstallation none of the desktop icons showed up. I have been able to find and make shortcuts for everything but the ROXIO Suite "Big R" icon.
