is there anything a chip offers that a dvd drive flash doesnt?
As far as im aware, a chip offers nothing when compared to flashing you drive firmware, i do know there is a chip or 2 meant for other purposes, "infectus" i believe is to do with being able to fiddle with and backup your actual kernel data and is also being used in a fairly recent attack on the 360 which people hope with some work/other hardware will allow us to downgrade any current and maybe future version of the kernel/dash to an earlier/vulnerable version..and so maybe get homebrew and hdd loading etc that we all want running. beware, i know little about this.

are any of the chip soloutions stable & offer at least the same features as the dvd flash soloution?
I believe the NME chip is stable and widely used to enable playing of backups in a fairly easy manner, however flashing the firmware still has an advatage..not only in cost, but also with the ability to easily return to stock, and also easily be able to upgrade to a new firmware should the need arise (M$ finds a way to ban us, and someone comes up with a counter)

i dont believe hdd playback is possible, media streaming, is this possible on the xbox360?
Playback of games from the HDD is not yet possible, and most likely a LONG LONG way off atm, although many teams are working non stop to crack the 360 itself, hold yer breath. Media streaming is possible out the box as long as your are playing WMVs...and if you install TVersity, or a similar uPNP server on your PC, your pc will transcode (convert on the fly) any unsuppoorted media to WMV so the 360 can watch it without leaving yer sofa. be warned semi decent pc required..and if you are thinking of transcoding some proper HD content..it might be time to invest in a supercomputer (IMG:
style_emoticons/default/smile.gif) my 3.33GHz dual core handles trascoding to 640 X 480 without any problems.

does anyone know any reason i shouldnt use a chip?
As above, its not as reversible/upgradable as flashing the firmware atm.

if u save ur original dvd flash bios & then reflash it, can it be restored to its virgin state?
Yes, as long as you backup the originalfirmware before writing the modded one, you can at any time go back to stock without issues. make sure you BACKUP your original firmware, as it contains a key that links the drive to the 360, and if you ever want to get a new drive, you will NEED that key.

can an xbox 360 be factory reset so no usage information is stored anywhere on it?
I have no idea on this one, im pretty sure its an unknown.

can u easily swop game / dvd playback regions?
Not easily, i believe if you have the exploitable kernel version (45** - "**" meaning sommit sommit, my memory fails me as to what number exactly) then you can do the exploit to get linux installed, then jump through several burning hoops, do a rain dance, and then get some info from the 360, which you can use to jump some more, and then change the regions etc. for me, its far too hard/complicated atm, but people are working on it, stay tuned and hopefully in time there will be ways.
on the plus side, alot of games seem to be region free, meaning you can play them on any 360.
Hope all this helps.
