Only one or two Suggestions. Maybe not worth to read
I am using Jaksta 4 years now to record c4 with a Firefox Macro for automatic use. The macro needs 5 Minutes to check my Favs (4 Tabs every 8 Seconds). Aber 1-2 hours Firefox or Jaksta crashed sometimes. Maybe memory things. Can you write a program to check broadcasters every 1-2 minutes and Jaksta records the online cams in the background. Your fabulous grabber don't work with jaksta. Your old C4 Downloader works great with Jaksta in the background.
