Hi,

I'm using a saa7134-based tuner card and its IR control. Most stuff works OK, except scrolling in mythmusic (and other menus) is jerky - how can I fix this?

I know it works OK using a keyboard (really smooth, fast scrolling)

To see if it was lirc's or the driver's fault, I did this:

pkill lirc
input-event 2 2> test.txt

I then pressed and held down the "down" button while continously pointing the remote at the receiver.

This created the following file:

/dev/input/event2
bustype : BUS_PCI
vendor : 0x1019
product : 0x4cb5
version : 1
name : "saa7134 IR (Elitegroup ECS TVP3"
phys : "pci-0000:00:0a.0/ir0"
bits ev : EV_SYN EV_KEY EV_REP

As you can see, there is a lot of "released" events mingled in-between the "pressed" events. Each time a "released" event came up, the output paused for a split second - in the same way as the scrolling menu pauses in mythmusic.

Any tips how to fix this, or even about where to look, are appreciated!

Thanks!
