I have a Denon 1910 DVD Player hooked up through DVI to HDMI on a Toshiba 37WL56. The picture through it is spot on, but every so often the screen will go black for a second and then come back on. I've tried hooking up my PC throught the same cables and I don't get the same problem. Would anyone know if this is the TV or the DVD player at fault here. I spoke to Toshiba tech support and they think it's more of an issue with the DVD player. The problem isn't that frequent i.e. once every hour or so and I cannot reproduce it by going to specific points on a DVD.
