Yours is hacked for sure if its saying custom fucntions (C.Fn) I started out with the 300d, it's a great camera to learn on. It's such a different camera when it has the hack installed. I upgraded to the XT cause I got a good deal but I miss the 300'd size.
Communication PIP and normal determines how it talks to your pc when you connect it to download photos. Some computers only see the camera in normal mode, some others see it only in pip mode. If you're using a card reader this option is worthless.
Wow ! Thanks Ogrt .. 
Ok .. soo err .. I am using a card reader (SanDisk Ultra II 1 GB card).. what other way should I be uploading the images? I'm assuming you're gonna say by direct plug-in from the camera?
And I'm not sure I'll ever use the MLU feature, as all I mostly shoot are models .. however, something about the ETTL, or .. I remember reading here (somewhere) where the hack is nice for an aftermarket flash? I cant remember .. I'll do a search and try to find the thread .. (it is here, correct?) that lists all the neat things that this firmware hack offers me with my 300D?
I do have the Metz 60 CT3 (2 of them) and would really like to get the 3102 and the 3000c modules, and get this bad boy lit up ..
I love the BG-E1 grip as well, really feels aLOT better, and my GOD, batteries last forEVER! This thing takes amazing images, and to have photoshop to enhance a bit of sharpness, and play a pinch with levels .. is an extra help.
I'm really lovin this site you guyz .. you folks are on the ball .. lots a talent, not to mention .. the knowledge here far exceeds any of my wildest dreams ...
Thanks !
