as jimmybee said, the emulator is rosetta, and it is part of the os and runs quietly in the background (aside from the length of time that it takes to open a non-intel friendly app, you’d hardly know it’s running). it will, however, eat up a chunk of ram. this will then limit the amount of ram that is available to the application, and this is probably the issue you’re having.
you can follow graham jones’ suggested settings (i think he was using the same amount of ram that you have), but his thread was primarily about increasing performance by limiting ram available to ae (in particular, ae7).
but you issue is not performance, it’s finishing a render, correct? there are 2 things that should help. make sure you are not running any other applications, particularly non-intel native apps like adobe cs2 applications. and, you may also need to try setting the ‘secret’ pref to pure ram at a specific intervals. hold the shift key and select after effects>preferences>general (hold the mouse key down the entire time, releasing on ‘general’). now, from the prefernce window click the pref pulldown and select secret (it may be shecret in ae 6.5, i can’t remember). set the purge every xx frames to a number that is less than where you get the error (if you want a generic place to start try 30). if you encounter issues again, lower the number by half, until you get a succesful render.
one other thing that can help, use the ‘send to render queue’ function, rather than make movie or export. if your render fails to finish and you used add to render queue… ae will will create another render in the queue that starts at the point where the failed render left off. you can then just reasemble the clips in ae or an nle.
there are two things that i would suggest… buy more ram. 1.5gb isn’t much anymore, i would recommend getting at least 3gb total (if you plan to upgrade to the next ae this summer you’ll want at least 1gb per core, preferably 2gb per core, so 4-8gb would be recommended to get the improved performance of the new render engine). second, upgrade to ae7… ae7 has a faster render engine than ae6.5, along with other improvements, and i think you will get a discount on the upgrade to the next ae. you got a faster computer, you might as well get faster software.

are you rendering via the render queue or are you exporting via the file menu?

do both pc’s have the same version of windows?
if the new one is vista, there may be some issues with the installer. check with adobe.
if they both have the same version of windows, then the only things i can think of are you need to have admin privileges, your computers are on a network and ae7 may be seeing the same ae7 on another computer (just pull one off the network).

you should leave your 24p footage as 24p (23.976) and not use interpret footage to change anything about the footage, unless ae is misinterpreting it. you said it’s progressive so ae should see it as progressive, so no field dominance or pulldown should be set (you would use those to remove interlacing and/or pulldown).
you should then be able to drag the clip onto the make comp button so the comp takes on all the attributes of the footage. then change the comp settings to frame rate you desire (29.97). now, when you render, set the render settings in the render queue to field render with the appropriate dominance for your 30i footage and add pulldown (i don’t think the type of pulldown will be important, you just need an extra frame for every four of your progressive frames).

make sure your render settings are using the comp’s frame rate (that is usually the default if you are using ‘best settings’). you might also check the output module settings… you will need to click the ‘format options…’ button, and make sure that is also set to the comp’s frame rate.
one last thing, are you checking the frame rate of the render in ae or another piece of software? another piece of software may may be misinterpreting an unusual frame rate.

i would try to shoot around compisiting problems next time, and go with static shots and cuts.
if you really need a moving camera shot, you should place some tracking dots on the green screen, but even this won’t make it easy. you’ll usually have dots that move behind somehing and you’ll lose the tracking, then you’ll have to track another dot to continue the movement, but offset the value so as to match the position of the previous dot. it can be a real pain. plus, if the move is too great, your perspective will change enough that you may never be able to match the background footage to the move.
at this point you could try to mimic the move with a 3d camera, positioning the background footage so that it seems like an appropriate distance from the foreground. or, just fake it, and keyframe movement of the background footage to create a believable motion paralax effect (it’s probably the easiest way). either way, if your camera movement is too great, you’ll start to run into problems.

if your render setting is field render off, as you say, then you are rendering 30p… set field render to the same as your source (lower by your description).
genearlly speaking you will want to set your render settings to the same as your source, this applies to audio as well, if you render with audio, make sure the render audio rate is the same as the audio in the comp.

photoshop does have better tools to handle selective bluring… filters like dust & scratches, remove noise and smart blur can be used to selectively blur some details but leave other others alone and can be very useful in removing the fine detail of the halftone pattern that is probably causing a lot of your issues.
google defilckerator, its a free action for photoshop that does a great job of only softening horizontal detail that creates interlace flicker in an image.

it is probably the pixel aspect ratio…. the dv footage you capture from your camcorder is nonsquare (.9 pixel aspect raition). for some reason ae is not interpreting it as such, but you can tell ae the correct pixel aspect by selecting the footage in the project window and right-clicking (or file menu)>interpret footage>main… here you can set the correct interpretation for pixel aspect (and other settings like field dominace–should be lower for ntsc dv). then when you put these into comps, ae will make the aspect correction for you, based on the comp’s pixel aspect.
you can do the same for images. you can also create or convert nonsquare pixel images in photoshop cs2. when you create a new file in photoshop, the file parameter setting window that first opens will have a preset for dv and d1 standard (and others) that are .9 pixel aspect. ps will then handle the conversion of images that you drag into the file (say a square pixel jpeg from a digital camera).
note that if you work with 720×540 sqr pixel images in ps (which is a very common and often preffered sive to work in for video), when you put those in a d1 or dv standard comp in ae, you will also scale the image down to 90% (or right-click (or layer menu)>fit to comp). that is normal.
