Many of our DaVinci (DM355, DM6467, DM644X) boards are built by Spectrum Digital(SD). Therefore, if you suspect there is a problem with the EVM, you should do due digleence to try and verify the suspected problem area (there are normally board level tests posted on SD Website). If you still feel there is something wrong with the EVM, you can fill out an Return Merchandise Authorization (RMA) form available on http://www.spectrumdigital.com/
