I have a pretty simple setup - file server with movies, HTPC in living room, various desktops and laptops. All the hardware is fairly recent and entirely capable of decoding 1080p h264. But for some reason, I get skipping if I try to stream 1080p movies over the network, and even with 720p movies, trying to jump to different parts of the movie takes several seconds to happen, followed by around 10 seconds of slow/fast sets of frames, distorted colors/blocking, etc., before things start displaying correctly and syncing with the audio.
I've tried: different video players (media player classic, WMP, VLC) and different codec packs (CCCP, Shark007). Out of ideas. (VLC works measurably better than the other two, but the issue still shows up.)
Specs: Gigabit network, i7 desktop, dual-core HTPC and fileserver.
