| I agree with Zeta. It’s a pointless endeavor that isn’t going to prove anything. |

| If you have a cheap TV that has a poor picture decoding NTSC, then the DVL unit could do better. Both are taking the NTSC signal and creating a component B/W signal. The only question is which one does it better. I have a Pioneer Elite Plasma and they had the best NTSC processing so I don't have to worry about this |

| Even the worst LD player with the worst LD still produces good luma. Luma is never the issue. |

You can likely combine the Y from the component output into the chroma from the Y/C output. It may work, there may be a timing issue or a ground loop. Thats not the thing that makes this pointless. It’s pointless because even when you’ve done the work it would be difficult to see or prove any increase in quality since both luma signals are really good.
Watch Psycho, Discovision, on an all analog LDV model. Seriously. It will look great. All of LDs problems show up when you add shifting compressed low res color on top of it.
Try running just the luma from each and AB testing the two. If you see any improvement then it may make some sense. I suspect they may look a bit different but likely neither is better than the other.
With NTSC the issue was COLOR. Not the actual outline. |

I guess it was probably a tough call. UMD movies have serious space limitations so having more than one stereo audio track was rare. They weren’t in a position to provide extremely similar audio tracks, like having regular stereo and cheesy surround versions of the same thing.
Two channel surround gimmicks usually produce distracting artifacts, goofy shimmering swirling phasing nonsense. Going only with a surround headphone track seems less correct…however…since there are no UMD consoles, actually watching UMD movies assumes you’re either wearing headphones or suffering with the built in squeakers. In that way using a headphone mix would made sense. I don’t know if anyone would have complained about it or cared one way or the other.
I don’t know about it being “worth preserving” though. UMD sound is not great. I can’t imagine wanting bad dated phase delay nonsense so bad that it would make me prefer something recorded in ATRAC3plus. There is always a newer better cornier fake surround system out there. You’d think if that was your thing that you’d just want a stereo version to run through whatever the latest gadget is. |

| Again, your really testing you TV input processing, not the LD player. But have fun playing with it anyway. |
