Recently I upgraded my TV to a full HD Philips. As this TV supported multiple refresh rates, I enabled refresh rate changer. TV is in "PC Mode" to get 1080 without overscan.
Now when playing TV (live or recorded), I get a large stutter every 1:40s. Skipping back 15s plays the stutter part cleanly so the TS buffer & recordings are fine. MKV's playing at 23.976Hz also stutter on a regular basis. The stutter "looks like" a whole lot of repeated frames, or a whole lot of frames played quickly as if something has gone slowly out of sync and needs to catch up.
Putting the TV into "HD mode" solves the stutter , but introduces overscan
Changing the refresh rate to 60Hz also solves the repeated stutter (PC mode) The picture when panning is not as smooth at 60Hz, but is preferable to the large stutter every 1:40s.
Graphs are smooth at 50Hz with nothing indicating any problems. Graphs at 60Hz are saw tooth as expected.
Im using SAF 6 and have tried almost every possible codec combination but nothing fixes it.
Im getting the same behavior in MPC-HC although the time between stutters is shorter at 20s, which suggests that its not an MP issue alone.
Ive rebuilt PC twice with same behavior
Render graphs for 50Hz refresh & 60Hz refresh attached, plus logs while set to 50Hz.
Any ideas or suggestions welcome.
