Unstable timer

[Ghostspirit]

Hi KMplayers.

When playing a song (.mp3) or video (.avi:XViD) (these are the only filetypes I had available for testing), the timer seems to be unstable.

1. Play media (mp3, avi)
2. Look carefully at the timer (see attachment)
3. Notice skips (on my machine it occurs at around 5-6 seconds, and then again at 12-13 seconds, and so on - with that pattern being pretty consistent)

I tried this with several skins, and confirmed that this isn't skin-related.

Don't care about it. It's just a nature of directsound renderer occurring as the the time slice of system clock is not exactly divided.
