VLC 2.0.5
I have few mkv files that are around 15 GBs. And when I skip form, let's say 00:00:01 to 00:23:05, VLC doesn't skip immediately, timer on both sides becomes blue (like buffering finished), and it stays like that for around 2 minutes and then video starts to play from skipped time. Checked with verbose level 2 in messages. No errors or some additional info. Checked with demuxing/muxing if container was not made properly. Same thing. This is for large jumps.
On smaller jumps audio stutters for a short period of time. About a second. Sounds like a sample was "triggered".
