Have to Kill RMC with Task Manager in Order to Exit

I turn on RMC4 to capture one program. It goes into record mode. I go to the web site from which I want to capture the web version of a TV show. I start the show. Everything works fine. In the meantime, Replay A/V8 is working in the background capturing other unrelated scheduled stuff. RMC4 starts to capture those streams as well. Then RMC4 says those streams are "complete with errors" and it's trying to convert them to MP3. (I have RMC4 set to convert FLV's and MP4's to MP3 so I can also have the audio available separately.) As a result, it won't let me close the program since it's still trying to convert something I didn't need it to capture anyway... so I wind up killing it with Task Manager. I told it to cancel the conversion, but it ignores my request and still says to wait for the conversion to finish.

FEATURE REQUEST: Be able to record/capture one stream and ignore all others that may happen to be present.

Thanks,
