I'm pretty sure my quick launch still works, and I always have the dvd dongle in port 4...using ava 48.4, PAL xbox (v1.1).... I'll try to remember to double check...you have to hit the quick launch button at the right time....too soon and it won't register, even if you hold it down, too late and it's too late....it takes a bit to know when the right time is....
My xbox was being rather funny yesterday afternoon....I'm not sure if this is a bug or something else, and I'd have to test it again to see if I can similar results....
Basically, several program loads and IGRs (using 4979.06), then some programs take a lot longer to load...my led is set to change red on load...it will stay red for a MUCH longer time than normal, but if you wait the program will load.
I was experiencing crashes upon program loads, where the led stays red...I'm not sure what fixed it....I deleted the ava settings via MS Dash (again, not sure what this does), and deleted e:\cache contents....but still stange issues...even my games weren't loading at one point....this is the first time i've seen this...I cleared everything again, and managed to get it going again...no probs since, but I still encounter the slow loads sometimes.
Try loading small apps then resetting, then reloading them several times...like dvd2xbox and enigmah video switcher...
Not sure if it's a bug/mem leak whatever, or some caching thing the xbox is doing, or what...just thought I'd put word out....didn't notice it on older versions of ava.
cheers all.
