I just fetched a clean copy of the current CVS source and tried to compile it
by doing

  cd driver
  make
  cd ../libdvb
  make
  cd ../apps
  make

as suggested in the INSTALL file.

What happened was that I get an error message from 'make'
in the 'apps' directory:

----------------------------------------------------------------------
In file included from av_pes2any/av_pes2any.hh:39,
                 from gdvb.cc:26:
av_pes2any/av_pes2anyc.h:42: ringbuffy.h: No such file or directory
----------------------------------------------------------------------

After changing this line in apps/gVideo/av_pes2any/av_pes2anyc.h:

----------------------------------------------------------------------
42c42
< #include <ringbuffy.h>
---
> #include "../ringbuffy.h"
----------------------------------------------------------------------

it compiled (am I doing something wrong here or do you have some settings
that are not in the Makefile?).

I then searched for the file named 'remux', but there was none.
Looking into the apps/gVideo/av_pes2any directory I saw that the make
hadn't done anything there, so I called it explicitly in that directory,
which gave me the following error messages:

----------------------------------------------------------------------
gcc     -c -g -Wall  -I../../../driver -I../  av_pes2anyc.c

collect2: ld returned 1 exit status
make: *** [av_pes2any] Error 1
----------------------------------------------------------------------

Again I have to ask if I'm doing something wrong here or wheter there
is still a difference between your current source and the CVS copy.

Greetings
Klaus
