[vlc] Re: HDTV Transport Streams (.ts) and Performance

[Galen]

Interesting. In the OS X GUI, there is a slider for this under modules 
-> decoders -> ffmpeg. I tried adjusting it, but it didn't seem to 
affect the stream much. There are also options for direct rendering and 
"Hurry Up" - both of which have no visible effect on the playback on my 
machine.

Is there any way to get the playing framerate? I have a 1920 x 1080 24p 
MPEG 2 HDTV stream that I'm working with. It is 2 MB/sec. It plays a 
lot better than the 60i streams do, it's approaching watchable, but 
still drops enough frames to be really obnoxious.
