That's why we're giving a built-in, in the machine, a try. The symptoms suggest, perhaps just the packet payloads are encrypted, and some port of the materials outside of that can be parsed. I already made a post with details on the Gyan FFMPEG download offering, so if the guy wants an FFMPEG.exe, it is available. You can use ffprobe.exe and dump the interleaved frames of information into a really big file, for examination. the compressibility of the file, the entropy, might hint at encryption, but it's going to be pretty close, because high quality video formats already "look mostly random". nine.ts 180,179,388 bytes nine.ts.7z 160,030,696 bytes 88.8% of original, using 7Z Ultra If the file sample does not compress that well, it could be because it is encrypted. Only if the Transport Stream was 100% encrypted, would it compress poorly enough to be noteworthy. If just the payloads are encrypted, the file will still be compressible. Just not down to 88.8% . Dumping the .ts into a hex editor, there weren't a lot of landmarks in there. The nine.ts sample had no 4CC codes. There was an occasional burst of padding. And there was a tiny bit of text string suggesting the short-form Guide Data for "what is up next on this channel". That is all I could see in the sample I have here. Our broadcast signals here (8VSB), don't use a lot of multiplexes. I have one signal I can get on an antenna, which is a multiplex of four, and the sub-channels would be SD. All the others are HD. But I don't have a PVR, and I have a tuner card, and my tuner card uses unencrypted .wtv for packaging (what is recorded to disk). Paul
