Unfortunately, the playback is slightly choppy on my Phiremod 5.1 CM7 Gingerbread OC’d to 975MHz.   So maybe this is why it’s not a supported device.  I’ll try again after updating to Phiremod Nook 6.2.  UPDATE: Playback is smooth after update to Phiremod 6.2.
Start with a rooted Nook Color… If you don’t have one of those buy it here then root it here and optionally get ROMSs here.
Remount /system as read/write
adb shell
mount -oremount,rw /dev/block/mtdblock3 /system
Edit build.prop to Spoof “Supported” Device
adb pull /system/build.prop  
Edit the build.prop and change these lines:
ro.product.model=HTC Vision
ro.product.brand=tmobile
ro.product.name=vision
ro.product.device=vision
ro.product.board=vision
ro.product.manufacturer=HTC
Finally, reboot
adb reboot
