read alot about how what you feed these screens is very important.
does this mean if i attach it to my tosh 330 and watch my father ted dvd its going to look ****** , or do i have to lash out a grand on a new dvd and only watch superbit transfers ????
Using an SD or HD Panasonic display you generally get out what you put in - as you do with a decent set of speakers!
You dont 'have' to upgrade your Toshiba DVD player - it will produce very watchable images on either of the Panasonic screens but given a better player the display will produce better results.
You also have to prioritise your budget - is DVD a big part of your viewing or is Terrestrial or more likely Digital TV your primary source; if yes then consider an external video processor from DVDO (IScan UltraHD) or Lumagen as a more sensible upgrade as they will benefit all of your video sources; and you can still revisit the DVD player at a later date if you like.
