@littlesat - similar problem exists for MinuteInput in seekFwdManual/seekBackManual there in InfoBarGeneric.py - it using Input.py too. There Is possible put big number and then e2 crashes.
OverflowError: in method 'iSeekableServicePtr_seekRelative', argument 3 of type 'pts_t'
There in Input.py should be some parameter for max number (default as None) and then fix limit in calling, imho.
