Hello,
i need to recover video recorded on hard drive which was inside this DTT decoder:
CDV-DVB-T PVR 3506

Filesystem is Tiny UDF but encrypted, i decrypted it with this tool:
http://www.ulozto.net/xsyReMD/sigmatek- ... reader-zip

now windows shows me UDF partition but there isn't quite nothing inside, very likely because filesystem is damaged.
I tried to recover multimedia files via RAW in R-Studio but all MPEG2 video seem damaged (all frames are very dark and with a lot of noises).

Do you know the proper way how to recover this kind of filesystem or at least how to recover multimedia files in RAW?




This is just what i see inside 'StorageLabs TinyUDF Volume' mounted partition with Sigmatek tool:


I physically imaged entire drive with WinHex:


as you can see on pic above bytes need to be inverted every 2, so i modified the image by inverting bytes:


I think what does Sigmatek tool is just inverting bytes in the hard drive on fly, as i did manually on the image via WinHex.
I'm not sure if it Sigmatek does something else besides inverting bytes

After that i created new image with swapped bytes, i loaded it in R-Studio but i can't find any valid multimedia file in RAW.
