I agree that this probably isn't a hardware problem - this is probably a Vista/Media Center/DVR-MS problem.

I have also had this problem with Heroes. Monday night both Heroes and The Tonight Show were bad for me. Heroes gave me a length of 8:14 and TTS said it was 9:11.

I downloaded that software to check out my metadata, but I didn't have any luck. There is a field named Duration, but it isn't editable.

For Heroes it gave the duration as '4943420000'. The Length property tells me the show is 8:14, which is 494 seconds. That seems to correspond to the '494' in the metadata duration field, but I don't know what the rest of the numbers would be. And like I said, the program won't let me edit this field anyways.

Matthew Toney - since you have supported tuners, could you post this problem in the "Ask Media Center Team" section of this forum? Jess usually seems quick to reply.

 

Anything is worth a try - I'll have to summarize the whole thing again (and I'll put a link to this thread in there as well) but I'll post it in that section later on today.

 

I'm experiencing the problem described here for tonight's Bionic Woman and my wife just told me that she used to have it occassionally on General Hospital.  The recordings were from my HDHomeRun tuner - Clear QAM.

My specs:
Vista Home Premium
AMD X2 5200+
2 GB ram
Tuners: HDHomeRun dual HD tuner (Clear QAM); Diamond PVR 550

Ok folks, I have posted a "summary" version of the problem (and this thread itself) over in the "Ask the Media Center Team" section.  Here's the link: http://thegreenbutton.com/forums/thread/214106.aspx

If you think I've missed anything in there, please add to it!

Thanks Matthew! That's a very good summary - hopefully someone will respond soon.

3 of the 6 shows that we recorded last night had this problem. 30 Rock, The Office and Grey's Anatomy.

"30 Rock" did it to me last night as well, although "The Office" worked fine for me - go figure. :(

 

I have the same problem, and it occurs with both SD and HD (although SD is much more frequent).  My setup:

Vista Ultimate
Athlon X2 4200
2GB RAM
Hauppauge 250 (x2) (Clear QAM)
HDHomeRun (Clear QAM)

My input source is Comcast cable.

This is really starting to annoy me.  I don't ever recall this happening in Windows 2005 MCE.

If you right-click the file and look at the properties, it should tell you the duration in minutes.  For me, the durations are always correct.

what are the WM/WMRVEndTime and WM/MediaOriginalRunTime

I'm looking at a half-hour show that shows the problem (just recorded a few hours earlier today) and this is what I see under properties for the file. (in Explorer - on the "Details" tab)

"Media Section":
Duration: 00:05:16

"File Section":
Size: 1.58GB
Date Created: 10/15/2007 2:30PM
Date Modified: 10/15/2007 3:03PM

Where do I find or what do I use to find the various WM properties you mention?

Got the utility - hope you can make some sense out of these numbers:

Show with the problem recorded today (30mins long):

WM/MediaOriginalRunTime - 18000000000
WM/WMRVEndTime - 633280717795030000


Same show (different episode) recorded yesterday without the problem:

WM/MediaOriginalRunTime - 18000000000
WM/WMRVEndTime - 633279853795030000

what's the WM/WMRVEncodeTime (sorry forgot to ask for that one)

No problem!

those #s are all correct for a 30 min show that recorded from 6:30pm to 7:02pm.  what happens if you cut a min of the beginning or end and create a new file?  does the duration correct itself?
