Hi Xoxez,

I can give you some info, for the fillers bumpers and commercials, I think they are still a work in progress and do not work at this stage, but you would have to hear from lunatixz to know for sure. I too am looking forward to playing about with this.
For the Guide list only going to 6-12 hours, Try increasing the Pagination Size (Configuration-Globals-Parsing) I have mine set to 125 which loads the EPG alot further, however this also increases the load time of the epg.
If the Channel Manager can't find any content and the Channel is empty, It will leave that channel out. thus only 2 of 3. Sometimes it can be a simple mistake in your playlist that can muck everything up and you end up with nothing. I had a playlist once that was set to load all tv shows with a genre match of Australia. The playlist looked fine, but it just would not load anything no matter what I did, I eventually, deleted the playlist and then made it again and it worked fine, don't know what I did, but sometimes things glitch. 
I would hope in the future there may be a switch or option or something in the playlist creator to add commercials bumpers and trailers somehow. I believe from what I have read that the old method was to create a playlist, of just trailers/commercials/bumpers, tell PTVL to ignore this channel when creating the EPG and then interleave that channel with another somehow. I guess this has to do with making playlists and this is a Kodi thing, not PTVL so i don't know how this will work. I guess time will tell.

Hope something there helps.

Yeah I'll have to try again I think but I have short 1 minute/2 minute bumpers/commercials randomly play great but I think the channel is somehow not noticing the shorter bumper size and doean't know how to put them in the EPG Guide being so small maybe? The 4-7 second clips. Just a hunch.

Maybe it couldn't find content with mulitple paths just with one channel it starts to play random stuff from the library that's not the playlist.

I'll try increasing the Pagination size though to see if the guide stays updated
