MCE Remote Skip (1 Viewer)

[Westmassguy]

I have a genuine MS MCE remote. The left/right arrows for skip work perfectly, and I use the default skip steps for these. The up/down keys jump ahead and back. There seems to be no rhyme or reason for how far it does this. Some AVI/Xvids it jumps 10 min, some jump 5 min. WMV files same thing, some jump 5 min, some jump only 2. Also, I can't seem to find any way to adjust these settings. Maybe I'm missing something in the settings? Not sure if this is a bug, known issue or what. Anyone else having this issue?
Thanks in advance
