Hi lamelde,
Thank you for posting and welcome to the community! There are a few download managers managers out there. I would google to see which ones are best suited for you. The CBS shows that you are speaking of, are you accessing them from their website? There have been a few community members that have suggested Aterlo Nightshift, which you can find here.

Thanks,
