Hi all I've been reading this forum for the last 6 months - since I became a member of the Hummy family! Happy with just about everything - except this! I've found that, if I record a programme in HD with 5.1 audio, then copy it to USB via Filezilla and Foxy, I keep the HD video, but the 5.1 audio drops to AAC stereo. If I watch the recording from the HDR it is still 5.1, but transferred to my PC and back again, I only have stereo. Am I missing something here? Keep up the great work!
