not sure if this should go here or even in this forum.
I have a Sony DAV S500 and on dvdrhelp the region free hack is as follows;
now the The software part of this is what does the 95 boot cd do? does it reset my OS? or is it temporary? Also does this seem like a proper hack?1. Build a Windows 95 boot disk. (If you're not on 95, you can get an '.exe' file from the web which will build one. You need to search Google for 'Windows 95 boot disk'
2. Download Winsamp here: http://www.veg.nildram.co.uk/remote13.zip This program will emulate an IR remote on your laptop.
3. Extract the package onto the bootable DOS floppy disk. (this step is very important).
4. Download this IR code file and place it in the same directory as the package above. This file holds the five necessary IR codes converted to the format used by winsamp.exe. http://www.selen.org/files/REMOTE.TXT
5. Next you need to find out what COM port your IR is on. If you know, great. If not, the help in the 'zip' above will tell you the IO address locations which correspond to each COM port. You can then use your BIOS config menu or PC user manual to tell you what the IO address is and the the info from the zip to give you the COM port.
6. Boot up your PC from the floppy disk and run winsamp.exe. If your IR port isn't COM2 you may override this by using an appropriate command line switch. For example, use COM1 by running 'winsamp C1'
7. Press the 'r' key to load up the codes from the REMOTE.TXT file into Winsamp.
8. Turn on the Player. Just as it starts, hold "Display" and "Stop" and and while keeping them pressed turn the volume knob to the right.
9. The screen will flash a few times and then a service menu will appear. Now back to the laptop....
10. You will see that the buttons 1 to 5 in the Winsamp screen are purple which means that they are usable. Press Enter with button 1 highlighted then button 2 etc up to 5. (Navigate with the arrow keys). After using some of the buttons (certainly button 1), you will see a cursor flash on the TV near the bottom left of the Service Menu. You can use this to check if the laptop is talking to the player properly. Let this stop flashing before pressing the next button. Alternatively, use buttons 1-5 about 10 seconds apart to be safe. The 'Data Reset' message will briefly appear in the TV (in my case after button 4, but I still pressed button 5).
11. Switch off the power to the player.
12. Unplug the player for 5-10 seconds.
13. Plug in and play any region!! (I had a UK machine, i.e. region 2 and have tested a US, region 1 DVD which played fine. From the messages above I'm pretty sure other regions will also be fine.)
I realise that hacking is not allowed on this forum but it is actually legal to post DVD codes on websites.
