As far as I tested, it gives the same results for me too :)

I think it seems like the right approach, thanks! :)

I mean (if I got it right), if there is no need to seek back and forth, and we
are running with "-cache-min 0" and "-frames 0", it will get the info and exit
ASAP.  Just like if "-nocache" was used. But if it needs to seek back and forth,
it will use the cache and avoid downloading two times the same thing. And it
will not wait to fill the cache, since cache-min is set to 0 and as soon as it
gets all the info it will exit. Or did I misunderstand something ?

The only thing I wonder is if the default cache size (the one used when
"-noconfig all") is big enough to avoid downloading when it seeks back and
forth. But I *guess* it should be enough, right ? :)


Just in case I will give it a try with more streams early next week (birthday
celebration over the weekend here :)), but it seems about right.




Thanks a lot,


Rodrigo
