Have the latest 5.01.54 Replay Media Catcher on Windows 7 Using Firefox 32.03

Most all my downloads work reliably and predictably with the major part of what I download...EXCEPT YouTube. I can not predict what kinds or capturing problems ill come up with

I change the Https to Http and sometimes I might get a download.

I checked allow https streams and that didnt work.

Problem is that sometimes it records a 20 second segment and quits... and at other times it records a whole 45 minute download Just fine...and at other times it does nothing. I cant trust recording You Tubes. Here is a URL of something I was trying to record but couldnt. http://www.youtube.com/watch?v=KLYE5I_-4tE

There may also be a Problem with me: I have concerns to download and install the media Catcher Security Certificate...ownership and authentication was not very matched up and looked quite out of sorts and suspicious when I examined the certificate...it also seemed to allow the owner to use it as a front to my machine and to allow about anything...so I deemed it a security threat to implement. Do some of you others feel you have positive experiences with the certificate ownership and its broad bounds? RPMC may work better with https at You Tube with it...but it sure doesnt look too safe to experiment with on as of last month.

Any Ideas how to make the YouTube videos always download properly...most all of my other downloads work reliably as expected.

Thanks for any insights to fix this up.
