Karyudo, it is daunting reading those kinds of replies. I do appreciate some of what you said, however for the main part you're talking from an assumptive point of view. I am glad to hear you have thought about moding an NTSC player, I don't generally agree with you on the complexity of moding it, I do only have a limited knowledge of electronics - however the concept is fairly simple. Yes you may want to mod a more expendable NTSC player.

However, for arguments sake - if the LD player does in fact actually read PAL discs correctly as is (which it may well do, I'm not sure on that though - mainly because I don't understand all the technical qualities of LD's and if the reading system for NTSC-only is different to one for a multisystem or PAL LD player), that means the only thing you need to change is the output signal. You would do this (to the best of my knowledge) by changing the frequency from 60hz to 50 (using a resistor). That in itself may well output an NTSC-50 version of PAL- which is not a standard signal, but may be usable as is. The next thing you would need to do is pass the data through a PAL chip instead of an NTSC chip.

Now theoretically, IF laserman desoldered the current NTSC chip NOW and then put a PAL chip in its place, you would have a hybrid player that plays NTSC discs but outputs them as PAL-60. This would give some increase in quality over standard NTSC on it's own, because the PAL system has better use of colour - and laserman knows that. That modification on its own would allow you to achieve a higher quality capture than is currently available through the player. The only thing he would then have to modify for playing PAL discs is the frequency, which can be done with a resistor. You could then tack on a dipswitch so the player is permanently multi-format (it would always be a PAL signal, though). Now this is all in theory. Now you are right, in that it may not be possible to make it play PAL discs anyway. However it should be relatively simple, and safe to modify it to output a PAL picture, and as that is more than half the modification in itself (which improves the player anyway by allowing it to use PAL's better colour system), maybe it is a feasible option.

Funding, well as I would have explained in my original post I am unable to help in those regards right now. I did provide LaserMan with TR-47's discs, and I could provide him with anything else I happen to come across. If anyone wants to send Laserman discs, and will send them straight to me instead, I will send laserman copies (for free), which would save LaserMan sending me discs instead. Also, I don't have any equipment, or money to buy the equipment needed to undertake the task myself. I do appreciate the involvement, commitment, time and money it takes to undertake such an assignment.
