Please test this m3u. Does it work merging the channels?
The index2500.m3u8 link is the good one.
Thank you!

Yes, ProgDVB Engine is turned on. It works fine e.g. in that constellation:

Channel #1 BAD Link
Channel #2 BAD Link
Channel #3 Link OK
Channel #4 BAD Link

but not in the other constellations mentioned below.
Should be easy to reproduce with any channel.

Thank you!

I found some constellations that will not work correctly when you have 1 channel name several times with different links (of which some are bad links) merged.

Example that is ok (the good link is played automatically):
Channel #1 BAD Link
Channel #2 BAD Link
Channel #3 Link OK
Channel #4 BAD Link ...

How can you group different channels with the same name and several links?
If there are 2 channels with the same name in a playlist but with different links, they are merged but not both links will be tried. If you choose the option not to merge them you get 2 channels with the same name #1 and #2 ...

Thanks for the answers.
I meant 404 Errors (Resource not found) - so just bad links in a playlist that are dead.

Yes
Sometimes there are a lot of channels not working in playlists. Maybe it would be an improvement (of course just as an option, not as standard) for some users. (If Error - jump to next channel)

Hi,
is there a way to automatically skip channels of a playlist with an error so that the next channel of the playlist is selected and so on until a channel is ok?
If not, is there a way to add an option in ProgTV for Android?

Thank you!
