What CPU do you have?

Here: 

msi:~/video/VDR# cat /proc/cpuinfo

What gcc?

Here:
msi:~/video# gcc --version
2.95.2


void cTS2PES::instant_repack(const uint8_t *Buf, int Count)

Still can't explain how that calling 
parameter "Count" can become zero.
That seems to be a "read only" variable.
I assume that it should tell the number of bytes in "Buf"

Maybe i'm fooled by printf:

esyslog(LOG_INFO, 
"ERROR: can't record MPEG1! -  Flag1 %x c:%d Count: %d found:%d Zero:%d Rekurx:%d"
                                    ,flag1
                                          ,c
                                                    ,count
                                                             ,found
                                                                     ,iZeroCount
                                                                              ,iReCurs);





I too wonder why the "slightest" code changes 
changes the behavior so much.

I added the volume patch to vdr.c:
vdr.c did remake and restart 
vdr reboots the card and berboots the ard
with that funny i2c-adapter error numbers.

removed the patch and remake only
killall vdr runvdr
/etc/init.d/vdrstart start
vdr now runs.


In this case it maybe be:
As long as the cpu is very busy "Count" is never set to zero.
There are always already data available when CPU asks for.
On a faster PC VDR with only two cards is not so busy remuxing etc.
so the chance that no data is available may be given?



One question is:
What is the difference between recording with the first 
or the second card?

One thread/two threads?
