Video skips when transcode buffer is full

Video skips when transcode buffer is full

Postby Drkovrload » Mon May 14, 2012 11:23 am

While streaming 720p video whenever the transcode buffer becomes full the video and audio begin to skip.

I've tried increasing the heap size to 2gb, increasing and decreasing the transcode buffer size, reducing video quality settings but nothing seems to work.

Streaming PC
Quad-core 2.42ghz
4gb ram
windows 7 64bit
100Mbps wired to router
PS3 also wired to router
