how can I download a recorded moovie from directv app to my external drive

Hi, @Craiova. No, we don't have an option to download content to an external drive since it's encrypted to the receiver. Also, the content is the copyrighted material from third parties. Copyright laws and other applicable laws protect copyrighted material. Check https://www.directv.com/legal/ to read more. Lynie, DIRECTV Community Specialist

Sorry, you cannot. 

if you had dish you could save to an external drive but watch from the external drive only if you still have the receiver--they will be encrypted to use only with your receiver while active and cannot play on any other device
