Generally i do not watch movies. If i do watch a movie it's almost always anime (often for some franchise i am already invested into).
I have considered downloading some movies mainly to gain access to some audio clips i can use for stuff (you can use audacity for that). I actually downloaded a movie once due to being interested in the soundtrack but then when i listened to it it didn't sound right, something was off, then i found out the audio wasn't actually lossless.
Sometimes there is some TV stuff i get interested in that isn't anime but even then i tend to lose interest pretty quickly. Often youtube has what i am looking for and i am not sure how much quality matters there anyway.
Looking at BTN, PTP and HDB the most interesting option for me is probably HDB since they do not have H&R rules and they have both TV and movies in high quality. I do like being able to quickly delete something i have downloaded if i really didn't like it (even if i keep most for long-term seeding) and even if i only seed say 60% on some tracker that should be enough with 1Gbps upload speed, etc.
It's going to take some time before i can join HDB mainly due to my RED account not being 2 years old yet. I might also have to limit how much i spend on requests to meet the 500 GiB upload minimum.
One issue with HDB is that you are limited to high definition only (not sure if that is 1080p+ or 720p+) which means that there might be stuff you want that they don't have. There is BTN but then you have to put up with H&R rules and having to donate to get immunity from inactivity pruning.
