This has been thoroughly signposted in the other primer material, but HD-FOX owners still seem to fall into the trap of expecting their budget purchase to behave the same as an HDR-FOX, so I thought it would do no harm to flag it up again. The HD-FOX has no internal hard drive, so if you want to use it as a PVR instead of just a FreeviewHD tuner you need to provide a USB hard drive (preferably "portable" rather than "external"/"desktop" so it doesn't need additional power), and prepare it using the format options on the HD-FOX settings menus. To make life easy stick to a 2TB drive or below. For further advice regarding drives, including use of UPDs (USB pen drives), see HERE (click), section 12. . The HD-FOX only has one tuner, so you can only record one service at a time and it won't give you the option to record another even if it is on the same multiplex. . The HD-FOX has no mains on/off switch (the HDR-FOX has one on the rear panel). On the other hand, the HD-FOX does have a reset button, hidden under the flap at the right hand end of the front panel (the HDR-FOX does not). . The HD-FOX has different firmware and a slightly different manual firmware update process from the HDR-FOX, so if you want to install official firmware or the customised firmware make sure you get the right files, and follow the update instructions pertinent to the HD-FOX specifically. . The HD-FOX has no media streaming capability to your network. This gap can be plugged to a certain extent using the custom firmware, the Mediatomb package, and decrypted recordings (see item 7). The HD-FOX does not have FTP capability either (again, correctable by custom firmware). . The HD-FOX can access other DLNA/UPnP server devices (including HDR-FOX) and stream from the network as a client, and it is the only client (apart from another HDR-FOX) we know able to negotiate protected access to the HDR-FOX and thus stream recorded HiDef content from it. This makes the HD-FOX a very useful remote playback device for another TV in the house: with your HDR-FOX and HD-FOX connected to your home network, all recordings on the HDR-FOX are available to the HD-FOX as standard (no custom firmware necessary). . All recordings made by the HD-FOX onto the external drive are encrypted, effectively locked to that specific unit for playback. There is only one way around this to obtain decrypted recordings which can be streamed using Mediatomb, accessed by a network share, or copied out by FTP (or other means) for use elsewhere: Install the custom firmware (for which you also need the external drive - see 1); Install virtual disk and BootHDR*; In the case of a HiDef recording use the auto-unprotect package to clear the protection flags; Run BootHDR to put the HD-FOX into "HDR Mode" - see Wiki entry Decrypt Recordings on the HD-FOX (introduction and Package Installation), and relevant forum topic HERE (click); Use the remote control handset to navigate the Media list and copy the required recording(s) to the virtual drive (on the USB device options) - this will decrypt them (copying using the WebIF media browser IS NOT SUFFICIENT, and if the red button offers you "move" instead of "copy" you are trying to send it to the wrong place); Reboot to return the HD-FOX to normal operation (non-HDR Mode). . * Note: you may need to set "development packages = on" in the WebIF settings to make this available in the packages list. Note also that while in HDR Mode, it is possible to save iPlayer/YouTube streams via the WebIF. . DON'T FORGET that references to decrypted download options, decrypt-in-place from the WebIF OPT+ menu, and unencrypt (automated decryption in the background) DO NOT APPLY to the HD-FOX. Sorry. Nothing we can do about it. Once you do have a decrypted recording though, options to convert to MP3 and extract MPG should become available (install ffmpeg).
