sorry to hear about your frustration.
make sure you have the Broadcom BCM970015 card.
did you use the crystalbuntu patch installed to the HDD?
ATV1 's with this setup are fast and wonderful
CrystalHD is a great on the ATV1 however it is based on the 8.04 unbuntu
Sam has promised an update to the latest by year end
the link below states the code s still available for 8.04 but you will have to manually recompile for the 8.0 variant...
