Recorded Show - No Video but has Audio on PCH

[jksmurf]

Recently I have had a number of Recorded Shows which when played on the PCH has no video, but does have Audio [on the PCH].

When I play the show using NPVR on the PC, the the same occurs (Black Screen, with sound), but if I jump forward a wee bit the show seems to work fine.

When I try to jump forward on the PCH it keeps jumping back to the start, as if the timeline is out of whack, so I never get to see the show; I just hear the audio.

• So first I ran the file through (free) Avidemux and saved as an AVI - on the PCH I got Video but no sound.
  
• So I then tried to run it through (free) MKVToolNix which normally works well, but it said something like the file didn't even exist and could not open it i.e. the normal audio and video streams never even came up.
  
• So I then ran it through a program I found called TS-Doctor and it seemed to fix it, so I imported it and it worked (even cut the ads for me, very cool) - I am not promoting the program btw, but I did buy it as my trial had run out.
  

Attached are logs from the two failed tests runs from the PCHA100.

What do you reckon, was it just a flaky recording? These are recordings where the computer is woken up by sub's great new double wake-event fix, but maybe with only 1 min padding it stuffs up getting a signal lock? I will try 2mins padding. The shows are recorded using a USB-Tuner; could it be the device being slow to wake up?

Sorry it looks like the file is bad, the PCH is not reporting a good incrementing time value, but I'd need to see the putty.log to really confirm. From the sound of things any good remux tool will work and extra debugging at your end won't help much. Also there is a commercial 15s which is generally not good for buffering etc. I think I have told you before mpeg-ts muxed in avi is a bad idea.

Oh. Bummer. The fact it is occuring more often (FTA DVB-T Channel), could this be a sign the Tuner is failing (I had an issue before with a failing tuner, those little USB Tuners don't seem to last long but Hauppage don't make any other kind for DVB-T); or maybe a poor signal?

Unfortunately I deleted the file, but will bear that in mid if it re-occurs.

Yes it did and OK. Just lowers the WAF when sitting down to a show if I have to race upstairs and run it through.

Also there is a commercial 15s which is generally not good for buffering etc.

Can I do anything with this by adding pre-padding so there is some decent show before skipping the commercial?

Unfortunately I have no control over this. It comes FTA through the tuner and onto the Hard Disk, it's not something I am trying to shoe-horn in :-)

In my comskip.ini, I use

Code:

always_keep_first_seconds=180

so that it will always keep the first 3 minutes of show as non-commercial. (NPVR and/or mvpmcx2 used to have problems if the first commercial was too soon into the show and 3 minutes was the recommended value at the time as I recall. It might be that a lower value would work OK now.)

Well whaddya know; this was in my comskip.ini! Erik must have done it a long time ago (GBPVR time).

Code:

always_keep_first_seconds=15    ; don't have first few seconds commercial so that GBPVR can get "in sync" (Brett had 180secs)

Cool! Ta - will try it
