SUPER for some reason makes it a maze to just find the download link to their software. Go to filehippo.com and search "super". Filehippo is just a site that host freeware apps. The website is simple and fast and doesn't make you jump through hoops to download. Good luck.

The software is quite simple. Everything is built in. Install. Run software. "right-click" and select your files. GO to OUTPUT and choose which device you have. They have a BIG list of devices. You don't need to have your device list, just a device with similar capability. There are alot of setting but you can just leave them alone. They are there are advance users who wants to control all the settings. Hope this help.

As for the stuttering of your movie in your computer, it's because you don't have the proper software to view it. I usually install FFDSHOW or K-Lite codec and it will help you to play the majority of online movies. You can find both of these at filehippo.com. FFDSHOW is probably simpler to use. Just install and forget about it.
