  1. Hello everybody,

    when I record some tv shows broadcasted via DVB-T using DVBViewer, sometimes some discontinuities happen like the one shown in the following screenshot.

    This is very annoying, especially when you want to record something you care about and wish to store.
    I usually try to fix these errors using either PVAStrumento, Project X or Videoredo and choosing the one which gives me the best results (often Project X).

    Here's my question: is there a way to perfectly fix discontinuities once they happen? I'm talking about, let's say, just one discontinuity in a two hour long file, in other words, not something so bad which would make the video unplayable.

    In the particular case of the screenshot above, for instance, is there a way to fix those blocks?

    Thanks in advance!

    No. The video looks as it does because some of the information needed to construct the video frame is missing, There isn't any consumer software able to restore the missing information automatically.

    Of course not. The compressed video stream was corrupted before it got to you. The only way to fix it is record the show again and replace the bad section.

    I'm assuming when you use ProjectX your are using it in Demux mode as this is the only mode that really attempts to fix transmission errors? If not try Demux mode and post the ProjectX log file. Generally if you have more than 24 errors reported then you are going to have visual or sync problems. Also it might be worth posting the X.ini file to take a look at all the settings.

    X.ini is normally found in the projectx folder but some installations put it in the temp folder under users.

    Yes, I use ProjectX in Demux mode.

    I attached both the X.ini file (I had to change the extension to .txt otherwise I couldn't have put it on here) and the ProjectX log file.

    Thanks in advance!

    Do I have to just create a new INI file pasting all of your settings inside?
    I tried doing just that and hitting "Quickstart" in ProjectX: I got the exact same results which I had gotten with the previous INI file.

    If there's anything else I can do, I want to thank all of you anyway for your help.

    Did you still get the same number errors with my ini settings versus yours? If so I think it proves there was a major signal glitch on the original. Apart from some "creative" editing around the breakup point there is not much you can do. One final thing if you can upload the TS file some of us may be able to try various treatments and see if there is a solution. What I suggest is pop it in ProjectX and edit top and tail to a manageable length and make an output using "To TS" rather than demux. This will leave the header intact and all the contents of the TS file. Good luck..

    Yes, I got the same number of errors, unfortunately.

    As far as "creative" editing goes, I did something kind of crazy: I was able to download the episode of the game show I had recorded from the official television channel website. I took the non corrupted frames (mostly the face of the guy speaking) out of the downloaded video, cropped the unnecessary parts away, positioned them right on top of the "discontinuity blocks" showing in my corrupted recording and blurred the edges only a little bit to blend everything together. It's not perfect, of course, but it's certainly better than before, I think.

    Thanks everybody for your help!

    No way ever. You can twiddle it, but it is not good afterwards.
