  1. How come ProjectX produces an audio ac3 file and PVAStrumento produces a mpa file? Try outputting as a .ts file ('Prepare >>", in the 'Action' line under the toolbar, tick the 'To TS' checkbox). Make sure you set the output directory to somewhere other than where your source file is first!!!

    With PVAStrumento, if you click the 'make ps' button rather than the 'demux' button, it will try to output a single .mpg file instead of the mpa (or ac3) and mpv files. If you choose to demux then you can either just re-mux the mpa and mpv files from PVAStrumento together using a muxer, like Imago, or many editing and authoring programs will allow you to load the video and audio files separately and will then mux them together during it's output stage.

    I've got both a Hauppauge PVR150 mpeg2 hardware capture card in one machine and a Hauppauge Nova-T USB2 Freeview tuner (DVB-T) in another machine, both using GB-PVR (the forerunner to NextPVR) to record. For quite a while I used PVA Strumento and MPEG2Schnitt - sometimes had to cut off the first few megabytes of the recording before PVAStrumento would load it properly. In the end I stumped up the cash and bought VideoRedo and have never regretted the decision. It's so quick to edit out the ads, it's frame accurate (for MPeg2), corrects many problems that might be found in an mpeg2 file, can correct the reported bitrate saved in the file's header, make the GOP size DVD compliant, and, depending on which version you get, has a basic DVD authoring package built in which can handle non-DVD compliant files. (e.g. 544x576 resolution files). I'm not linked to VRD or anyone who works there but, apart from Windows, it's probably the most used bit of software on my PC.

You WILL need to find and follow the guides for both of them as they're not particularly intuitive but they were designed for just the problems you've been seing. As for your CUDA probs, weren't there problems with the nVidia 8??? cards and CUDA? I'm sure that's why I went for a 9600GT over a 8600 or 8800 card a few years ago.
    ProjectX don't work as it produces a full lenght video file but a shortened audio file. For example, a 60 minute video running through ProjectX produces a 60 minute video file, but only a 20 minute .AC3 file. Any ideas why it does that?

    And when I run the TS file through PVAStrumento it produces 2 files, an .mpa and .mpv.

    What do I do with those 2 files now to create an MPG?
    .ts files often have transmission errors in the audio, the video, or both. The shortened audio file from ProjectX could be the result of audio errors. Maybe the ProjectX log can tell you what happened.

    .mpa is audio .mpv is video. You need to re-multiplex them for an .mpg. ImagoMPEG-Muxer might work.
    ImagoMPEG-Muxer doesn't work, it just remux for 2-3 seconds and stops.

    You could try Avidemux, and see if it works better for multiplexing. ...or you could do what TimA-C suggested and have PVAStrumento output a .mpg file using the "make ps" button.

  4. If you use AviDemux you must type in the filename extension. AviDemux won't automatically add it for you. Open the source, leave both video and audio in Copy mode, set the Format to MPEG-PS (A+V), and name the output file Whatever.MPG.

  5. It should be pretty clear by now that you have an original TS file with errors in either the audio, video, or both.

    Without taking a step-by-step approach and doing some analysis, the other alternative is to rely on blind luck to find a program which will fix the errors.

    You have gotten as far as achieving a full-length video file, with shortened audio. This is not failure, this is partial success. Half of the problem is potentially solved. You may note I suggested working with Video ONLY and Audio ONLY much earlier.

    Now, you can continue looking for a simple way to fix BOTH audio and video at the same time, or it may occur to you that IF you check this latest full-length video-only file and it is usable THEN you only need to find something that will yield a full-length, usable audio file and then stitch them back together.

    It is a process of trial and error. Without some research on the error itself, you are left with trying various file operations in various programs and hoping you hit on one that will fix the problem. I will recommend AGAIN that you work with the audio and video seperately.

    Here is an example py script which will do it... create a folder py inside custom folder in avidemux and add this script calling it something like remux_ts_2_ps.py

    # convert all ts file in intputFolder ending with extention to PS folder with _conv.ps extension
    # ...
    #
    ext="ts"
    inputFolder="c:/recordings"
    #
    def convert(filein):
    fileout=filein+".mpg"
    print(filein+"=>"+fileout)
    if(0 == adm.loadVideo(filein)):
    ui.displayError("oops","cannot load "+filein)
    raise
    adm.save(fileout)
    print("Done")

    #
    # Main
    #
    ui=Gui()
    adm=Avidemux()
    adm.audioReset()
    adm.audioCodec("copy",28152032)
    adm.videoCodec("Copy")
    adm.setContainer("ffPS","muxingType=3","acceptNonC ompliant=False","muxRatekBits=30000","videoRatekBi ts=25000","bufferSizekBytes=500")
    #
    list=get_folder_content(inputFolder,ext)
    if(list is None):
    raise
    for i in list:
    convert(i)
    print("Done")

    At the risk of being shouted at again, I'll make another couple of suggestions/comments:

    1).. The MobiDTV USB stick comes packaged with a dinky little stick antenna. Are you using that or are you connecting it to a full-sized rooftop antenna? Is it possible the reception drops off a little during a capture & that's enough to upset some transcoding sofware & not others. I agree with Nelson37... I think your .ts files may be the problem.

    2).. Reading the posts at http://forums.digitalspy.co.uk/showthread.php?t=553416 it seems drivers may have something to do with MobiDTV recording problems.

    3).. I believe the MobiDTV comes packaged with recording/viewing software. Have you tried using that instead of NextPVR just to check if there is any improvement.

    4).. PVAStrumento's .mpa & .mpv streams can be read into something like MPEG2Schnitt for editing & then re-muxed with ImagoMPEG-Muxer. Imago works well with SD streams but doesn't like muxing HD streams.

    5).. You can't adjust audio track timing in Freemake.

    6).. I see your opinion of Video ReDo has changed since we last spoke. If it works then maybe it is worth the $'s to get this problem resolved.

    1. It's connected to my digital antenna on my roof.

    2. Solution?

    3. Yes, but the recordings aren't smooth, but with NextPVR they are 99% perfect.

    4. Imago only works with SD channels, and not my HD channels.

    5. Can't be bothered. I just want to load and remux, end of story.

    6. Yeah VideoRedo ended up being good after I tested it for a full 15 days. But not worth buying for the occasional file I need to remux. I use Avidemux 2.6 experimental now which works on 9 out of 10 files.
