jjeff, I don't have any direct experience with hacking the Samsung 850: my reply to larryccf concerned the general notion that hacking the MV function in a player would make it possible to dub DVDs from it. In my experience with several old DVD players this was not accurate: killing the MV allows dubbing to VCRs but not necessarily to DVD recorders (which can still sense the secondary post-VCR signals not affected by the MV kill hack).
, hacking the Samsung 850 was very common and does not damage the unit. I did not realize how old
the 850 was: I thought larryccf was talking about a much newer player when I responded to his post (that I was shocked it could have its HDMI hacked at all). After doing a bit of digging, I see now that 8 years ago there were problems with a lot of expensive HDTV projectors that predated HDCP not working well with then-new HDCP compliant devices. So some mfrs included a back-door hack that would indirectly disable HDCP (in Samsung's case, the excuse was they couldn't unlock Region Free without also unlocking Component Upscaling, disabling HDCP and killing MV).
Apparently there are many variations of the 850 so the hack doesn't work consistently on all of them. Some owners had to repeat the hack several times before it "took." Combing thru multiple posts, each with a different tip, leads to this overall hack procedure:
Disconnect any HDMI cable from the 850.
Connect component cables from 850 to TV,
Use 850 setup menu to choose Component/HDMI connection.
1. Turn your television ON
2. Turn the DVD Player ON
(You should see the Samsung screen saver appear on the TV)
3. Ensure the DVD tray is EMPTY and CLOSED
4. Wait for the message 'NO DISC' to appear
5. Press the ANGLE button
6. Press the numbers 4, 3, 2, 7. You may or may not see "HDCP Free" flicker on your screen after hitting 7 (depends on player production date).
7. Press the OPEN/CLOSE button to open the disc tray. Wait 10 seconds.
8. Press HDMI Select and scroll to 720p or 1080i
You should now be able to select and view upscaling resolutions via component and HDMI, player should be region-free, and HDCP should be disabled via HDMI. MV may or may not be disabled: reports vary
