Realistically, these are bits of a video stream, not your bitcoin wallet or some other bits where security it of the upmost concern. Were talking millions of dollars of equipment to find a collision in SHA1 today....
How exactly is a 160 bit hash too short? Collisions can be had after 2^80 trys in naive scenario and 2^57.5 with an active attacker, not exactly easy...
Torrents can be, and often are, executable. Many Linux distributions are available over Bittorrent, for example.
Breaking crypto, especially new crypto, should pass a much higher bar than "not exactly easy". 2^57.5 is not all that large by the standards of a big cloud provider or a government.
