I have read all of your information and have found this site to be very helpful, thanks.

1.Does the Panasonic 50PX600U pass the deinterlace and 3:2 pulldown test?

2. Does the Pioneer 5070HD allow display at 72 HZ ?

1. Yes (deinterlace); no (3:2 test)

2. Yes

Will this set(or similar sets) display a true 1080P signal if and when a 1080P signal is broadcast over the air?

Thanks,

Although your Sony does not have the best signal processing in industry, the image you will see on HD DVD will be better than anything broadcast ,  thanks to its higher bit rate. You should experiment to which way it looks the best, setting the output of the player to 720p or setting the player to 1080i and letting the Sony HDTV downconvert the signal.   By the way the new Toshiba HD DVD player (HD-XA2) will have the Silicon Optix HQV chip which will properly convert  native 1080p recording to 720p output.

I haven’t purchased “guns” (CRTs) in awhile. If I recall correctly it used to be $75-$300 per gun plus about $300-$400 labor. My advise is ,if the set is over 7 years old don’t put any money into it. If it is younger the most I would invest is $500 in repair, remember you when get a 5 year old set repaired ,you end up with a 5 year old working set, something else can fail.’

 Half brightness (the industry standard measurment) is 15,000 hours with the set properly adjusted .

Probably, he would need to take the standard def output of his cable box or TV (usually labeled monitor out on TV) and connect it to the DVD recorder. Most DVD recorders accept S-video and composite a few acceopt component.
