Sparkee & kornchild2002, as most of your content is destined for playback on a TV, I'd recommend you read my post re: anamorphic encoding
. The methods I detail there will give you "effective resolutions" of 852x480 for 16:9 NTSC content and 1024x576 for 16:9 PAL content, which will look *much* better on a TV than 640x352 or whatever you wind up with when limiting your encodes to non-anamorphic 640x480.
One caveat: iPod 6G, Nano 3G and Apple TV will do 480p/576p, but the Touch is currently limited to 480i/576i TV output.
BTW, re: bitrates... per my comparison tests (using 720p source) 480p encodes plateau at about 1500kbps, and 576p encodes plateau at about 1700kbps (with 2-pass encoding). Above those bitrates the files obviously get bigger, but I personally see no improvement whatsoever, even zoomed fullscreen on a high-resolution computer monitor.
