If you're looking for an archive copy of the recently-rediscovered long-lost MST3K episode and you want better quality than YouTube, it's available at https://archive.org/details/0003-star-force #MST3K
I haven't watched it yet. It's bound to be rough both in quality of video (apparently it was an VHS recording of TV) and in riffing because they really hadn't figured stuff out yet during the KTMA season. On the plus side, I can confirm that it contains footage from Star Force which isn't in the later MST3K episode covering the same film. Is that better? Ymmv.
He tried to kill me with a forklift (in the preceding film)!
