[no Bug] DVD subtitles mal-rendered with VMR9 (1 Viewer)

[omerfarukozer]

When a DVD with subtitles is played with VMR9 as video renderer subtitles are displayed wrongly. Sometimes the colors are wrong, sometimes the outline of characters are displayed wrong.

I have attached 4 screenshots 2 of them are taken with VMR9 and others are taken with EVR. Subtitles are displayed fine when EVR is selected.


To reproduce the problem:
1. Choose VMR9 for Video Renderer in MP Configuration > Codecs and Renderer.
2. Play a DVD with subtitles

Probably not a bug in MediaPortal, since MPEG2 decoder is handling the subtitle decoding and EVR mixer (MS component) is handling the subtitle mixing to the video surface.

How can I test this outside the MediaPortal?

When I play the DVD with Windows Media Player everything works just fine. Both video and audio are decoded with NVIDIA. I have attached the screen capture. As you can see subs are OK and NVIDIA is using VMR9.

Which OS are you using?

Okay, you are using XP, so you should be using VMR9 as renderer.

You need to provide complete logs. You entire MediaPortal.log consists of

You can manually build the Directshow graph with GraphEdit.

At first I would recommend you to try some other MPEG2 decoder. NVidia's MPEG2 decoder has been not supported by NVidia itself for many years. Not sure why it would fail with MP in the way you are describing, but using a deprecated codec is not recommended.

I have generated the logs with MP Debug. I will check the log verbosity and post new logs.

I remember trying ffdshow. It did not solve my problem. Tonight I will give it another try and post the results. Is there a recommended codec for DVD playback?

One last question: altough I have filled my computer specs they are not added my posts. Do you know why?

You need to tick the option to show them in usercp

The problem was NVIDIA codecs. I have changed DVD codecs to MPC and now subs are fine.
