I have Mac OS-X 10.11 (El Kapitan) Will creator work for me?

I'm trying the trial version to see if this is the right program for my needs. I need a blue ray with menu creator. My question is, after I created my menu and burned sample videos on a blue ray disk, why doesnt that custom menu show up? When playing back all I get is black screen with play movie and chapters. All the menu and title bars are gone.

I can't seem to find a site where I can downlaod a video. I want the actual video not just the audio.

I need to buy a HDMI to Audio Video converter to enable connection between my laptop and old generation analogue TV. Where can I buy this converter in New Delhi or NCR?

I checked out a CD from the public library and listened to it on my computer. Then I dragged two songs into my iTunes library. Is this illegal, since that's loaned stuff?

I want to make DVD to VOB for ripping DVD to VOB video for playback on compatible devices. Who can tell me how to finish it? Thank you.

I have been trying to get this video done I made but the files are so big and HQ that they lag my software!
They are MP4 and they are HUGE. I have been trying to get them done for the past 2 days but haven't been able to because of the slowness it causes. So I want to downgrade the size so it will help me to create the videos easily.
I am currently using Freemake Video Converter, but that sodding bastard took 6 HOURS to convert in WMV!!!!
So I don't want to go through that again... What is the fastest and best converter? And what format should I convert from MP4

just purchased a movie,  i can't play it on my iMovie.
iTunes said the media is protected by DRM.
How can i do?

converting a video_ts file which is on a harddrive at 4.6 gb, but it converts to mp4 format at 95.5 gb.  Any help please?
