When I found out that Optoma was taking over the entry level projector market – excuse me, I mean introducing a 720p DLP projector for under $1000 – I quickly lined up a unit for review. You heard correctly, this is a 720p-native DLP projector that is debuting for $999 (street price). To suggest that this projector might be a popular item going into the holiday season and throughout 2007 would be like saying that Reality television might be getting a bit stale. I’ll just say it now – this should be the top-selling projector of the coming year, and for good reasons that I will outline in this review.

This was a problem with the DVD player. I now have the oppo 970HD and the component cables work fine.

What kind of time frame does it take for this to happen?

Great review, what led me here was a problem with my HD70 that I think may be easily corrected. I have 25FT runs of both SCART/Component and straight component cables - each of which I have hooked up to my 5-7 year old Sony DVD player (dont have model # handy). My issue is that during indiscriminate times or scenes, the HD70 will “drop” the image completely with its blue splash screen, 2-5 seconds later, the image comes back. I have tried it with a SCART/Component cable as well as the straight component port and the same thing happens, even at the exact same moment in the scene on the DVD. I ran DVD over SVIDEO and no signal problems at all. My HDMI source (cable TV) has never dropped either.

Is this a cable problem? A signal degradation problem? a projector problem? If I had a spare DVD player that was easily removeable, my plan was to move it closer to the projector and test a different DVD player with a shorter cable, but I haven't been able to do that yet. It seems to happen with action scenes/sequences, and less on dramatic slightly moving images.

Any ideas would be greatly appreciated.

I have the same problem it drops in and out. I have the Sony DVD S5550D and the HD70. It works fine on S-Video. My cable run is aprox 33 feet. The image on component when present looks great. Is this a cable problem or HD70 not being able to hold on to the sync or maybe just the DVD player.

Convinced by your article…

Clint, after reading your article I went to BBUY to pick up my HD70 but when I arrived they had the Sony Cineza HS51A for the same price on sale. Should I go for the new DLP technology in the HD70 or for last years model Sony? Which would give me a better picture? Many thanks for your help!
