I was under the impression that in order to make working backup copies of HD, files the procedure is to use FOXY to modify the htm file copied from the Hummy and then copy it back to the Hummy. This works fine for me and the "enc" flag is removed. I can then copy back to a USB stick using the recorder's copy protocol, and the decrypted file on the USB stick plays ok. But this is incredibly slooooww! However, having backed up all my valuable video files from the Fox-T2 directly on to an external HDD using FTP, I have discovered that I can decrypt the htm file which is on the external HDD using FOXY and then copy it back to the external HDD, and the video then appears as decrypted and will play directly from the external drive. At no point have I recopied the modified htm file back on to the Hummy and then copied from there to a USB stick. This obviously works, but I was surprised that it does. Everything I have read seems to imply that recopying the decrypted htm file back to the Hummy and then using Opt+ "copy" to a USB stick is essential. So, do I actually have working decrypted videos on the external drive which will play on any HDR-FoxT2, or am I missing something obvious? All contributions gratefully received!
