iPod 5.5G scrollwheel responsiveness - any work being done?

Not sure where to post this, so sorry if it ended up in the wrong place.

Have had Rockbox on my new 80GB iPod Video for a few weeks now, and I find Rockbox superior to the iPod firmware in every respect except scrollwheel responsiveness. This single issue makes Rockbox on the iPod feel clunky, despite its awesomeness in all other respects.

I think I read somewhere that this is due to limitations in the scrollwheel driver, but now I can't find that post. Is this correct? If so, is there any work being done to update the driver?

tdtooke:
If you don't mind building from source you can find "#define WHEEL_SENSITIVITY 4" in firmware/target/arm/ipod/button-clickwheel.c.  Set that to a lower value.  You'll have to play around a bit to get it just the way you want it.

Could you define what you find wrong with the scrollwheel behaviour? Too slow? Too fast? Something else I can't imagine ?

Nicke2323 may be experiencing a different aspect of unresponsiveness but what I've noticed is that there are times when rotating (along) the wheel doesn't result in a smooth scrolling of the line selector (while in the file browser, for example). That is, if I move my finger along the wheel at a "medium" pace (no idea how better to quantify this, maybe in terms of RPM? :)) the selector won't move proportionally, sometimes it even jumps, and it takes a lot of rotation to have the selector cover a relatively short distance. There are other instances, however, where the wheel works as usual, wherein it is extremely sensitive and you can cover long lists in just a quick flick....

Zardoz:
In general it works well for me but there are times when it seems strange - scrolls slowly, jerks or jumps, scrolls too quickly, doesn't respond at all (particularly the menu and select buttons, but also the scrollwheel.) I thought I just had a dodgy scrollwheel, I can't imagine why it should be so intermittently odd
