Please try whether this patch works with all the HD channels you can
receive.
I would also appreciate if as many other VDR users as possible applied
this patch and tested it, so that we can be sure it works before I release
the next developer version.
The patch fails on vanilla .30, do you have other patches applied to
remux.c as well?
Sorry about that. There was an intermediate change in there that has
become obsolete by this latest change.
I have attached a new version.
