9 directories, 637 files

Notes:

• .cache appears to have a cache of images, mostly show frame grabs. 6 directories, 2 files
• The .dat files appear to contain EPG data in a proprietary format. I am not publishing them here, if you’d like to probe at them, join the Discord
• .umount-proc-info is probably the most interesting thing from this dump, and it gets its own page: umount-proc-info

└── .umount-proc-info

13 directories, 8193 files

Notes:

• The .cache directory is interesting because it has album art for a lot of music, even though music was never intentionally used on this DVR.
• The .db files are SQLite databases.
• umount-proc-info
• The version file says 0.9.6.
• Recordings.dat suggests that this partition is mounted at /mnt/hd2, since it holds file paths for the recordings.
• For each recording there is:
  • .ts: video streams
  • .hjs: unclear
  • .njs: unclear
• Recordings and Media are accessible over SMB.

Partition 3: hmx_int_stor

    │   └── manifest
    ├── download (ISO Media, not as in the disk image format, probably a streamed video of some kind)

    └── .recycleBin (empty)

Nothing interesting here, honestly.

Partition 4: the LUKS one

Probably the rootfs. I do not have the password.
