120Hz?

[CTho9305]

While watching olympic high diving, I noticed that it looked really awful on my setup during the portion where the divers were really moving fast and also when NBC wiped their logo rapidly across the screen. I captured the raw stream to look at it later, and I don't think it's just my setup: shot 1 shot 2 (I scaled the images down a bit, but didn't do any deinterlacing or post-processing). If the whole point is to make fast motion look better, but the content providers over-compress the data anyways, does the 120Hz frame interpolation help? Is NBC's olympic coverage just particularly bad or is all live content like this? Do you only get a benefit from 120Hz when watching Blu-Ray movies?

Do you use OTA or cable/Satellite?

I've been watching OTA. I have cable, but the OTA quality appears to be about the same as over cable (I'm pretty close to the broadcasting towers). The OTA bitrate appears to be about 16Mbps, which should be close to the max for ATSC.

Wow, that actually looks like your TVs fault.

The second shot shows that your deinterlacing is completey fubarred (combing on the edges). Something about your TV's processing looks really messed up. Can you return it?

The shot isn't deinterlaced, and it's scaled down slightly (which makes it look a bit strange). The deinterlacing appears to work fine. I'm complaining about blockiness (which 120Hz can't help with, right?), not the interlacing.

Well I am seeing a lot of compression on the olympics coverage, but the severe combing in your second pic is your TV's deinterlacer.

This is with deinterlacing enabled.

That looks entirely normal. Welcome to the world of macroblocking...enjoy your stay.

I have the same problem, but not quite as bad as your pictures indicate.

atleast those huge pixels come out crystal clear on your HDTV

Dose your TV support 120hz ? Very few did when I bought my Samy plasma and it was one of the reasons I bought it over a Pany. I havent looked at the Plasma or LCD Tv's for a couple years so I don't no if they all support 120hz now or not.
