[vdr] Unable to rebuild index on some French HD records

[dplu]

Hi

When we delete index file on some HD recording due to synchronous problem for 
editing, sometimes vdr is not able to rebuild it , start for few seconds and 
generate an errors

Stream has "something" in it, you can add mark but not navigate between 
without crashing vdr , when playing records, time goes not seconds to seconds 
but every two seconds

Is it possible for next release to increase the buffer size to 300 instead of 
100 in recording.c , class cIndexFileGenerator ? This has been tested 
successfully by at least two users with same problem

Thanks in advance
