Then I tried using AVISynth 2.51 and VirtualDub 1.5.1 to open a script (below) but got the error message "Couldn't locate decompressor for format 'YV12' (unknown)" and it goes on to say I need a Video for Windows (VFW) codec. So I tried installing MarcFD's vble video codec (beta version).zip (linked here) thinking "well, that's a YV12 codec" but that didn't seem to help.
Install DivX5 or one of the recent builds of Koepi (a stated in the AviSynth v2.5 FAQ).

I should warn you that this plugin downmixes to a two channel audio. Of course you can also mux the AC3 with VirtualdubMod.

I thought the problem might be that I was using VirtualDub 1.5.1, so I installed VirtualDubMod v1.4.13_2 with needed_DLLs_251102 and AviSynthLexer_0_1.zip, but when I first open vdmod, I get the License agreement, acept it and it crashes.
Empty the plugin dir of AviSynth and try again. If that doesn't help install VirtualDubMod v1.4.13_1.

Lastly, I decided to simply add ConvertToRGB32() to the (above) avisynth script, and VirtualDub 1.5.1 was able to open it just fine.
That's because Virtualdub 1.5.1 can't handle YV12 clips, while VirtualdubMod (in fast recompress mode) can. This is all stated in the AviSynth v2.5 FAQ.
