No audio when News comes on

I was cutting some commercials & noticed when there was also a brief News "commercial" inserted, or at the end of the recording when the News actually started, that there was no audio. Not a big deal since I want to delete the News, but I'm curious why is there no audio?

Is it transmitted on a separate audio track?
How could I find this information? When I play the original OTA .wtv recording, my A/V receiver indicates DD5.1 for the program & the News.

I copied the .wtv file to the PC which has VRD on it & converted it to a .dvrms file.

I did some checking & the .wtv file plays the News with audio when using WMC on the PC that has VRD. However I'm using the .dvrms file with VRD. So I tried playing the .dvrms file using WMC and there is no audio with the News.

So the problem comes from converting .wtv to .dvrms. Again, not a big problem since I'm cutting the commercials & News.

You can check Tools->Show Program Info. However I think the conversion process from WTV to DVR-MS removes all but one audio stream, so even if it did have another stream it was likely stripped when you converted it.

I just upgraded to VRD TVS V5. I've only played with it a short time & it has solved my audio problem & also an issue with a missing frame number.

I did a QS Fix & was overwhelmed by all the format choices in which to save a video.

The main reason to use WTV over DVR-MS is that WTV can hold H.264 video. If you're only ever editing MPEG-2 then it really doesn't matter. They are essentially the same when it comes to MPEG-2 video.

I've read that H.264 kept file sizes relatively small & that MP4 was widely accepted. So I tried saving a WTV video using the H.264 MP4 option. That was a mistake. I realize there was going to be some conversion taking place but didn't expect all 4 cores of my CPU to run at 90%. And the processing status bar barely showed movement so I aborted it.

Would that high CPU processing be mainly due to converting from mpeg to H.264 or from changing from WTV to MP4?

Almost certainly the change from mpeg to H264. Normally just changing the container ( mpg, ts, mp4, Mkv etc) is very quick. Although I think you should probably be posting in the V5 section of the forum now.

If you have an Intel CPU try the QuickSync option. It uses a special H.264 encoder built into the GPU portion of the chip so CPU usage will be low and processing speed will be a lot faster.

The PC with VRD on it has a quad core AMD CPU. For now I'll save the edited video in the WTV format.
