Here's mine....
I like the sound of Nasif Bhai's work with the XBox. I'm currently thinking of upgrading my K750i firmware to W800i. Thats as far as I'll prolly go with tweaking
. But I'd love to tweak the DVD player my parents have in Dhaka to play XVID and DivX avi's. I bought that for $25 from a store here, and is great for playing MP3 CDs and VCDs too... just that it'd be way easier for me if it plays my .avi files
