    I’m just getting started with mpc digitize. I have installed beta 0.3 on both Windows 10 and Windows 7. It seems to walk through my recordings, but then it fails with same error as it’s parsing:

    Any workarounds for this?




    The app crashes exactly when xml metadata files are being parsed. Depending on how many recording do you have, maybe you can open some of the xml files stored in \mpconverter\metadata folder and check tag


    This tag should not be empty.

    The file name is incorrect too
    Years of Living Dangerously_NGCHD_2016_11_23_21_59_22.wtv.xml
    it should be
    Years of Living Dangerously_NGCHD_2016_11_23_21_59_22.xml

    Clean \metadata folder
    Create new folder
    edit file \settings\
    change “inputfolder” location
    Copy 1-3 recorded files to this new location
    Start application

    It should create new xml files

    Open Folder Options and remove check next to Hide extensions for know file types.
    See if the xml files have actually 2 extensions wtv.xml.

    Remove .wtv from file name

    Start application and see if Left panel loads with recordings names

    I believe that the only way to fix it is to actually make some adjustments to the way xml files are written or read. I will provide solution to this issue in the next beta release.



    Sorry – I only posted the last few lines of the log before. I actually have about 200 shows in my Recorded TV directory.

    I did some more digging. My Recorded TV directory has extra files in it (EDLs, XMLs, VPRJs and logs for commercial marking and skipping). I think those might have lead to the excess suffixes.

    I also might have a few recording with errors (8 of my recordings have the hostname in the file name – not sure if that is an error or a sign that there is a copy flag on the file).

    I copied 50 recordings to a different folder and MPC we able to parse that clean folder that only had .wtv files in it.

    Does MPC Digitize limit itself to only .WTV files?



    It’s OK, the information you provided gives me some idea about the issue. I think I know what is causing additional extensions, however the files that have hostname in file names are completely different thing.

    Why do u think these files are corrupted?
    Can you play them in VLC or Windows Media Center?

    Do you have any clue why these files have hostname instead series name?
    What is some manual recording?

    The way program works it scans input folder and gets file names and paths. Only WTV files are processed next. Metadata is extracted and put into xml files stored in \metadata folder.

    After it is done, application parses xml files from \metadata folder.
    This is where error occurs.

    Based on information you provided error is caused by empty date string from xml file.

    If you can, please copy/paste content of xml file from \metadata folder for one of this files with hostname in file name.

    You can also run a test by putting these files in separate folder and scan in with converter. If application crashes, then we would know that they are main offenders.

    Also you can put EDLs and other files together with WTV (except for files with hostnames) folder and scan it. This would confirm that they are not causing any issues.
