I have installed Premiere Pro CS6 on my home workstation (RENDER-PC). When I log in using RDP from my laptop (DAVID-LAPTOP), the audio and video stutter (oddly, they are in sync, they just stutter).

When I export the video (720p, 5 Minutes, 29.97 FPS, encoded as an AVI, NTSC DV Preset), it renders perfectly in under 2 minutes.

If I play it back in Windows Media Player, it plays back fine.

What is the reason for this? Its the same video, just in different programs.

EDIT: This also happens if you play a video in Chrome. It stutters, but downloading the same video plays back fine in Media Player.

EDIT2: Here are the Export settings in Premiere

Not entirely sure about the details, but Windows Media Player is likely using the video streaming option of recent RDP protocol versions – it reads the compressed video file and tells the OS to stream it over RDP directly, having the client decompress and render it.

Meanwhile, other programs (unaware of RDP) render it server-side, causing each individual frame to be transmitted over RDP, decompressed. This obviously requires far more bandwidth (that's why the original video was compressed in the first place), causing some frames to be dropped.

(RDP does have some compression, but it uses different algorithms. It's optimized for program interfaces which have quite different requirements; loss-less since you wouldn't want a program to appear blurry; transferring frames in 256x256 tiles instead of whole frame; and so on. It doesn't work well for video.)
