QAM HD shows recording in 480i

[sixdoubleo]

I have Comcast and am receiving QAM channels via an HVR-1600. The last few days, I have been getting recordings that Sage marks as 480i...yet they are shows that I KNOW are supposed to be HD.

Sage is grabbing the right channel, and it actually marks them in the recordings list with the "HD" icon, but if you check the Details of the recording, Sage says 480i @ 29.92fps.

The quality seems to be HD, or pretty close when I watch them...but I don't have the best eye for that. The file size is consistent with HD.

Is there some way I can check these files to make sure they are actually HD?

Does Comcast sometimes transmit a "less-than-HD" version of a show over QAM?

This brought up before in "HD recordings listed as 480i".

Basically, SageTV samples the file to figure out the resolution and sometimes the sampling hits a low res commercial giving a false reading.

You need a bigger TV if your eyes can't easily tell whether or not its HD. That being said you can alway just open the file in Window Media Player or the like.

Excellent thanks. Yeah I was hoping it was just a commercial or something that was fooling it. I open this particular file in VideoRedo and it says it's 720p, so I'm good.

I'm on a 67" as it is! Nah, I can tell the difference....but given a few of the issues I've had getting HD working properly, all of the sudden I got shows that are smooth as silk AND Sage flags them as 480i and it had me thinking maybe they AREN'T HD.
