Topic: DVD Video stutters when SVP is enabled

Playing a DVD on Potplayer, the video stutters (like playing only 1 frame every 1 second) when SVP is enabled. It plays normally when SVP is turned off.
This is the video information:

Is there a setting somewhere to fix this? I don't get this problem with normal mp4 files, just DVDs.
The videos on the DVD are 29.97 fps. I don't know why it is being reported as 25 fps.

I got the same glitch when playing the DVD on MPC-HC as well.

I'm setting the Framerate Conversion to "Screen", and I'm using the "Display Mode" auto-switching in MadVR. So normally I'm using 120hz. And when this DVD starts playing, it changes my refresh rate to 100hz (as it detects the video to be 25 fps.)

Does anyone have an idea of how to resolve it? I've lots of DVD ISOs that have the same issues with SVP but play perfectly on my Android Media Player. (It detects the videos as 29.97 fps correctly).

please show SVP's log

Re: DVD Video stutters when SVP is enabled

I disabled the auto-switching in MadVR before opening the video:

Re: DVD Video stutters when SVP is enabled

However, when I tried to open the .vob files directly from the DVD, they play normally without any problem. But if I use the "play disc" from the menu or similar, it glitches.

Re: DVD Video stutters when SVP is enabled

ah. in this case you probably need to set proper deinterlace mode in the video decoder, i.e. NOT doubling the frame rate
