Converting the Sony RDR-GXD500 digital-tuner DVD-recorder to multi-region involves sending it five special custom-programmed remote codes. These are the same codes that are required for the Sony DVP-NS355 DVD-player, so if you do a web search on that, you can find ways to program these codes into a Palm Pilot, or a laptop with an IR port. But the cheapest way, if you don't already have one of those is with an OFA remote which costs about £20. Here's the process: Get a One-For-All universal remote that has a DVD key and a "magic" key, such as the One-For-All-4. * Select DVD device on OFA remote * Hold magic key until double flash on DVD key * Enter device code 0533 The RDR-GXD500 DVD recorder must be set to command mode "DVD1", and its own remote set to the same mode like this: * Switch on recorder and point its own remote at it * System-Menu -> Setup -> Options -> Command-Mode * Select DVD1 * Set remote's Command-Mode switch (under the cover) to DVD-1 * Verify that recorder can be switched on and off with both remotes Now program function code 189 into button 1 of the OFA remote like this: 1. Hold magic button until double flash on DVD key 2. Press 994 3. Press magic button (don't hold) 4. Press 189 5. Press 1 - double flash indicates success Advanced OFA remotes such as the Kameleon have five digit function codes, in which case, press 00189 for step 4 above. Now program function codes into buttons 2-5 like this: * Repeat steps 1-3, then 255 2 * Repeat steps 1-3, then 095 3 * Repeat steps 1-3, then 221 4 * Repeat steps 1-3, then 079 5 Now the actual conversion of the RDR-GXD500 DVD recorder to region-free: * Put DVD recorder on standby and point OFA remote at it. * Press 12345 - "TIMER OK" is displayed, and recorder starts up * Press 12345 - Recorder goes back to standby The RDR-GXD500 DVD recorder is now multi-region. Clear the OFA remote by removing its batteries for a while.
