I've made a layout for 2 IR-LEDs based on oPossum's single-sided Layout.
It measures 1.05" x 1.5", which should fit into my housing.
I'll etch the PCB these days but unfortunately my laser printer doesn't work and I have to print the layout with an inkjet, so the quality isn't that good.

Just a comment.
Fatten up the V+ and GND lines as much as you can. A decent amount of current is flowing through the IR LED's and they're fast transistions.
See if you can move the power input pins to where your electrolytic is at the top of the IC. This will shorten your power traces to the IR led's AND the IC and also minimize the power droop at the MCU since the IR LED's won't be in the same leg of the trace from the power connector.

This is the second version with some shorter and fatter lines and for a external pushbutton.
Maybe they're some other improvements but I think now it's ok

As mentoined.. The LEDs are working when I put the Transistors to +, what the MCU normally should do. Tomorrow (21.21pm local time) I'll test everything I'm able to test..
It just could be a teeny-weeny (what a funny word for a German) problem and I'm overlooking it.
But I'm confident.. as sure as the rivers reach the sea (Yep, that's a great simile I think) my TV-B-Gone will work!

Aha!
Now I've got it
"cause ur english us so good" - I only learn BANNED-English in school, so sometimes it's a problem for me to understand American expressions
And I don't want to swank about my English-abilities, but I'm not that good in
American English
Okay guys, I'll inform you when something has happenend

A little bird told me it's raining cats and dogs, but the details were a lick and a promise. If your TV-B-Gone doesn't work, I'll eat my hat!
Heh, our language is wwweeeiiiirrrrdddd.
