Hi,
is anybody else experiencing sluggish response to remote control commands? It started when I updated to kernel 2.6 and VDR 1.3.
I did a quick test tonight and ran both irw and vdr in parallel, to see whether it's lirc or vdr that's dropping my remote control commands? I could reproduce the following situation: I pressed the menu key while watching live TV and irw correctly showed it. vdr did not react. I pressed the menu key many more times and every time irw correctly showed it, while vdr just rarely brought up/removed the main menu. In between, I also pressed up/down sometimes and vdr always reacted to that key.
Has anybody else observed this bug? Any solution or workaround yet? Would you suggest that I put some test code into VDR to debug it?

Yes, same for me. But I am observing that remote control key presses are never lost. Sometimes I press several keys in sequence and nothing happens. After some seconds, the keys are "executed" very quickly.
This behaviour is very annoying sometimes.

I am also using lirc for controlling other applications (e.g. yammi) and the reaction is always fast.

I also thought about some test code. But I have never looked into the VDR code yet.
I think, there must be some instance inside VDR which "caches" the remote key strokes in some kind of queue.

Yes, you are right. Of course, for a toggle key like "Menu" it is sometimes hard to say, but I agree - it looks like they are never lost, just delayed sometimes an the executed all at once.

It may be the lirc demon which is buffering them and vdr may just not get around to reading the lirc queue all the time.
@Klaus, is that possible? Any suggestion where I should start looking?

VDR buffers up to 16 keystrokes in cRemote::keys[].

OK, here is an update: I added this

to lirc.c / remote.c and waited for the problem to occur.
A few minutes ago it did. I pressed Menu to bring up the main menu and Down a few times to get to "recordings". The main menu came up but the cursor did not move down. I pressed down many times for almost a minute. No effect. I waited a few seconds and the cursor skipped down all the way to the last main menu entry. My log shows that vdr has received my commands when I pressed them, not all at once like it would seem from their effect on the screen. This also exctly matches Dirk's description:
