Calibrating a Motorola 6412 HD-DVR
This is probably a difficult if not impossible question to answer, but here goes:
I'd like to as accurately as possible calibrate my Motorola 6412 HD-DVR, which is connected via component to my Sony Grand Wega III.
Now obviously it can't play calibration disks or patterns (i.e. I don't have a pattern generator, etc.), so my question is:
Is there a DVD player (HD or not, etc.) or other device that anyone knows will closely resemble the picture settings output of the Motorola 6412?
I'm essentially looking to hookup this player to the component input the 6412 is connected to and calibrate with CalMAN, SpyderTV and GetGray, and then reconnect the 6412 and hopefully have a pretty closely calibrated HD input for watching TV on.
Thanks,

In Canada, I do not have access to those channels. The only HD patterns I have access to (when they appear) is some basic SMPTE patterns displayed on the CBC HD channel.
Are there any known devices that can play calibration disks that someone knows resembles what the Motorola 6412 puts out? that way I can rent one
and then use it. I know it won't be perfect, but I don't think my Panasonic RP-42 dvd player is close to what the 6412 is.

It will be hit and miss using a DVD player.
Consumer devices can be good and bad. The more expensive analog DVD players tend to have the more accurate performance, but there is no guarantee your Motorola is going to be very good over analog either, but they are usually close. DVD players also frequently have many settings than can interfere with black level which is the primary issue with adjusting each source. You may be better off just looking at some dark program material on the 6412 and set the brightness based on that.

Ok, thought it might be tough to do. Hopefully the CBC will put something up I can use, but I don't think they are useful to do a SpyderTV & Calman, etc. calibration, just an eyeball one.
Most DVD players can be acceptable for as a source for calibration, but the levels may be off some. However, the SpyderTV is not an accurate product for that display. I took some readings with one on my GWII and it was not close enough to use.
What if I use it on this display with the CalMan software? Why is it not accurate?

Click on the link under my signature. The results for the probe shown is very similar to the SpyderTV.

Very interested. No doubt the Eye-One Pro is more accurate on my TV than the SpyderTV. However, in your opinion, will the SpyderTV/Calman calibration on my TV be more accurate than eye-balling settings using DVE (including allowing me to do a more advanced grayscale calibration)?
My issue is price. I have "borrowed" a SpyderTV and plan to return it, and the Calman software is only costing me $100. This is far less than $500 as I only plan on using it on one TV and likely only once.

It is your call.
You just need to be very suspect of any color readings. It is very useful as a light meter to adjust gamma but I would not trust it for gray scale. It may be better than you can eyeball, but I is worse than several other methods including just purchasing a Kodak gray card and using it as an optical comparator with indirect daylight as a light source.

Maybe using it with a Kodak gray card to compare with might prove adequate for my purposes. Thanks for the advice UMR, you are good.

And what light will you use to illuminate the Kodak gray card?

That's the right answer - but the question is where are you going to get a 6500K light source? Use of "indirect daylight as a light source" is questionable as daylight is variable (From 5,200K to 20,000K - depending on angle, how overcast the sky is, etc.). Further, indirect light will be heavily influenced by the color of the walls in the room, etc.
You can purchase 6500K lamps (that was really the answer I was looking for), but I am not sure how accurate they are. But they are probably much more accurate than indirect daylight.

More of a slightly different question: For general lighting for a lamp in the room (I watch with one 60w bulb in a lamp and everything is calibrated with that light on), is there an ideal bulb I can use? What's the best generic light bulb and wattage to use for watching TV in a room with my TV (42WE610)? Again, I can't watch in perfect dark as I have kids and need to keep some light on in the room.
I'm currently using one of the Phillips daylight bulbs (resembles daylight as per packaging).

I just need a lightbulb, but only see long bulbs here.
Any suggested light bulbs or at least a good wattage?
