Right, but the HDHomeRun app will adapt the framerate so you will get the occasional duplicate frame or dropped frame as the app works to make the 50Hz local playback speed match the 50Hz broadcast rate (both are 50 frames per second but the length of a second is not the same between the two). This is the same as when you watch content mastered in the USA - frames are dropped or duplicated to make the output 50 frames per second for EU broadcast.

Yes please - that would help.

Ok, any way to disable this then, with a toggle in settings for instance ? I know it will be out of sync but at least a option to try if it works without stutters ?

I recorded this footage (check your PMs) broadcasted at 50 Hz and slowed it down (the 1st frame drops is due to my phone camera). You can clearly see stutters happening between the 14-15 sec when you look at the ticker and the sentence "voir conditions détaillés [...]" : the image stops = frame drop (?).

Thanks for the camera phone footage. The video seemed to slow down and the audio disappeared - was the video edited?

Do you have this content in a recording we can test here?

Not sure of what you want. Yes I edited the video by purpose to better highlight the stutter at the end of the footage. I used the x4 slow down camera mode.

Do you want it but not slowed down ?

EDIT : I sent you via PM 2 more footages : one with the HDHR app source (stutters), the other with the OTA tuner beta source (no stutters, couldn't manage to cancel the x4 slow down on it).

Hi nickk,

Did you manage to get my footage (cf. above) and note the stutters on your Shield ?

If you can't see it, I can send you other footage with the latest HDHR app, which is (for me) unwatachable because it stutters every sec.

Well, no news about the issue.

Can we at least have an option to stop the HDHR app matching speed between 50 Hz local playback and 50 Hz broadcast, as you explained above ?

Checking, have you tried the new 20210728 release?
