How is it possible for the "Technisat TECHNISTAR K4 ISIO" receiver to record 4 programmes simultaneously via a USB 2.0 (type A) connection? With this amount of data? USB 2.0? Doesn't this require at least USB 3.1 Gen 1 (even better Gen 2)? Can anyone in the community confirm that this is indeed USB 2.0 as described (as of Dec. 2020) AND that 4 programmes can be recorded simultaneously without artifacts? Thank you for the confirmation!
