The Sony 12HT does not to the best of my knowledge have a DVI connection. The TW100 has almost every input you would need except perhaps SDI.
The TW100 gives a great picture IMHO and it seems that the new Sony 12HT is also good according to other threads in the forum. If you can get the two side by side, that is probably the best way forward to making your final choice.
Both PJ's can suffer from pixel problems, so be sure to buy from a source that will support you in this respect.
