Okay, wonderful! This gives us a solid lead to figure out what's going on.
Just a guess, but Windows relies a lot on the file extensions and it could be using the wrong parser thinking an .mpg file is an MPEG2 Program Stream instead of what it really is, an MPEG2 Transport Stream.
Try changing the file extension from .mpg to .ts and see if Windows gives a valid length.
Also right click the file and look at Properties->Details.
I wonder if the "Windows Movie and TV" app has any logs? I tried searching for logs from Windows Explorer but didn't find anything. If we can get some sort of error message from Windows it will help clarify what it doesn't like about our files.
I don't think the .mpg file extension is causing the issue. All recordings from Channels DVR have .mpg file extension. OTA recordings never had this issue. Certain TVE recordings such as movies don't have this issue.
One thing I have noticed when looking at the properties is the frame rate is very high. The movie recordings that are good show a frame rate of 29.97.
With my very limited understanding, the discontinuity indicator is set if the current stream packet is in a discontinuity state. This could be the continuity counter or the clock reference. But I'm pretty sure that only applies to MPEG transport streams.
Best I can tell these are unhanded stream errors that are being passed in the re-encoding??
There is definitely something different about the files that are being produced my Channels DVR?
Possible container conformity issues?
Some info direct from the source on File Type and Property handlers in Windows.
i.e. what displays the Length of a video in Windows Explorer.
File Type Handlers
https://docs.microsoft.com/en-us/windows/desktop/shell/fa-file-extensions
Property Handlers
https://docs.microsoft.com/en-us/windows/desktop/properties/building-property-handlers-properties
Is more information required on this issue?
I'm running into this problem semi-regularly. My workaround is renaming the .MPG to say .BAK, which circumvents Windows Explorer from thinking it's a video filetype. If I run the offending .MPG is run through VideoRedo QS-Fix, for me it finds and corrected audio sync issues. If I rename the .TS (output from VideoRedo QS-Fix) back to .MPG and put it back in the recordings directory, life is good for another day or two.
On my system, files follow the discontinuity_detected > 0 pattern described above; for example:
2019/07/29 22:15:03 [MTS] Statistics for "TV\Legion\Legion S03E06 2019-07-29 Chapter 25 2019-07-29-2059.mpg": skipped=0 unhandled_packets=0 discontinuity_detected=8 transport_errors=0 invalid_pts=0 invalid_dts=0 saw_pcr=false saw_pmt=true highest_pts=4542.892978
VideoRedo QS-Fix output
Is there a detailed log file available from the videoredo session that shows which resync frames were removed and why?
Also, if you tell VRD not to detect/fix resync (Tools>Options>Stream parameters>Detect / resync missing frames), does the resulting file still hang Explorer?
When I change the VideoRedo Stream parameters->detect/resync missing frames option to ignore, the audio resync frames are removed as before. The resulting file does not cause an issue with Windows Explorer. The length column in Explorer comes up quickly vs the original recorded file which hangs Explorer for minutes while not displaying any value in the length column in Explorer.
We've reached out to VRD to see if they can shed more light on what's happening here.
We've also been poking around the Windows logs to get a more clear indication of what Windows doesn't like about our files, but so far no luck.
Saw your posts on their forum and the request for VRD logs.
Any progress?
Since I also use VRD (not sure if you do) and have access to ChannelsDVR TVE, I could also provide example logs if needed.
IIRC, one of the two Dan's over there could probably use ChannelsDVR TVE as I think he has COX which DRM's everything. Good to see you're collaborating with them.
I'm not sure if this is related or not, but this past year I used the utility "streamlink" to download several program streams from Watch ESPN. I assume the methods it uses are similar to the ones used for TV Everywhere recordings in Channels DVR. All of the programs I captured via this method exhibited the same symptoms you describe here. If you went to the folder and even clicked on one of them in Windows explorer it would cause explorer to permanently "hang", and require you to force close or restart it. Those files wouldn't load in VideoReDo in the traditional manner either. I ended up having to use TS Doctor to repair them, and then use those repaired files with TMPGEnc to get a workable file. If anyone happens to have TS Doctor, or can supply one of the "problem" recordings you're having trouble with via Dropbox, etc. I'll be happy to run it through TS Doctor to see if the log file it generates will help you out any with this issue too?
What does that mean?
Did it fail loading the file, or did you get errors when trying to QSF or Save As?
And is this the TS Doctor you mention?
http://cypheros.de/tsdoctor2_e.html
Yes, that is the program. In my case opening the file in VRD would just hang forever and I’d eventually have to force close the program. Quick Stream fix also failed with errors.
Curious how did you QSF the file if VRD wouldn't open it. And do you remember which major version of VRD you used? 3,4,5?
OK, I just did my first TV Everywhere recording and had this occur. I recorded an episode of "Mama's Family" off Logo. When I try to open/view the file properties in Windows Explorer it hangs until I force close it. If I open the file in VideoReDo it loads, but when I try to watch/edit it I get a message saying the "Resolution has changed" from 1080 to 720 and it offers an opportunity to run the Quick Stream fix. When I try to do that it ends with an error and no output. I renamed the .MPG to .TS and open it in TS Doctor. It says "important PCR Missing" and asks if I want it to fix it. Even after the repair it still gives the resolution error in VRD, but Windows will let you click on it without an error and display a run time now.
Here is what my Channels DVR log said about this recording:
Statistics for "TV/Mama's Family/Mama's Family S04E25 1988-01-15 Mama Goes Hawaiian 2019-08-02-2151.mpg": skipped=0 unhandled_packets=0 discontinuity_detected=46 transport_errors=0 invalid_pts=0 invalid_dts=0 saw_pcr=false saw_pmt=true highest_pts=2376.845322
I think what is happening here is the same thing that happened with my ESPN streams from streamlink. The program provider (in this case Logo) is taking a program feed that might be 1080, and then inserting lower resolution commercials during the stream. This causes different resolutions in the same file and confuses the heck out of VRD and Windows explorer.
Here is the log from TS Doctor:

Duration: 00:00:04The latest v5 of VRD handles resolution changes.
In fact they have v6 out now.
What version of VRD are you using?
I'm using VideoReDo Professional 5.1.3.746. It says my version is up to date. I think VRD Pro runs behind the consumer version though.
