Begining from about version 20.0.63 I have the player occasionally freezing, when activating "Tempo & Pitch" DSP on videos. Not via the checkbox in the list of DSP's, but when I begin to change the Tempo control, it changes the tempo and activates the checkbox. But the player hangs up(not always).
Though, if I do this when the video is paused, it never happens.
And the second problem, is that the DSP tag doesn't work on videos for "Tempo & Pitch". But it works perfectly for audio files. So I can tag the playback speed of audio and it preserves for this file's playback.
