[RelentlessEffort]

Thanks for the reply, I thought I had enabled debugging to give you relevant information, I will check again this afternoon.

Is it normal behaviour for this add-on to add blank spaces in the guide? Or to populate varying amounts of content instead of filling the guide? I was under the suspicion that errors parsing Json data (in some of the logs I posted in this subforum) were responsible..

I have noticed the character [/B] displayed in the guide in the left pane under video preview. Is this an error with PTV or ITV?

Uninstalling did stop the crashes, because there was no more PVR to use.

I modify my library frequently and I have seen issues detecting library changes, recognising NFO information for custom channels and issues communicating channel information to ITV (building channels).

Please consider looking into this when you can, I will help with any logs I have

Please read the project Readme you'll find answers to common questions there.

If you need help with a specific issue I'll need a full log, thx

 
After some more testing, a Kodi database issue was to blame for missing shows from within a genre, I renamed the folder location of my video source and re-imported, did a library clean and this issue was resolved.
I am still experiencing the following issues:
1. Channels built will leave empty guide entries and crash when attempting to play those entries. 
2. Channels will skip while building before reaching 100% and this seems to reflect how much content is populated to the channel before blank entries are seen.
3. Playlists of shows will only play episodes from the first show entry when added as custom channels (eg. if you select a playlist with American Dad, Family Guy, etc. the only episodes played will be from American Dad).

How is the pagination setting used in PTVL? I increased it to max assuming it would pull more entries from the database to populate the guide, but this was not the case for all channels. It caused channels to build much slower and would skip most channels before reaching 100% built, but after modifying the PVR settings to 0 previous days and 2 future days, some channels have now populated the guide completely.
To give some clarification, the remaining channels with blank entries have limited content, does this explain the missing entries? If I have one channel with a single episode, instead of repeating the episode it only plays once and then Kodi crashes?
Now I feel like I have an explanation for the issues I've been experiencing, if this is the case, could you please create a setting to repeat content until the guide is filled? This would've made a lot more sense to me and prevents crashes.

I assume the 3rd issue is explained by shows playing through in alphabetical order (in my playlist random order is selected but only applies to episodes in PTVL)
