Is there a reason why DVD ISOs seem to take 5-10 seconds to open across a wired 100mb network under Linux XBMC when they open almost instantaneously on the same network, attaching to the share SMB share, on XBMC for XBOX?
I can "open" the ISO... the remote goes unresponsive (but seems to be buffering keypresses)... 5-10 seconds later the machine comes back to it's senses and opens the ISO and tries to execute any buffered commands received from the remote.

Authentication doesn't seem to be the issue... everything else (including multigigabyte mkv files) plays instantly across the network.
So is this a problem localized to my rig, or is this something that is a know issue that other users are having?

2 of 3 fileservers I can reproduce this problem on are linux based (Thecus N5200 and Unraid). The other is windows XP...
and BTW for clarification.
SMB=CIFS its just the name of a protocol that IBM and MS invented circa 1982. It used to be commonly called netbios or netbeui which were both also not really correct.
Samba is an implimentation of this for unix.

I've got 680 DVD's stored on an SMB share as ISOs. I can tell you that if the menu system in the ISO is complex, it will take as much as 30-40 seconds for playback to start.
Thats why when I ripped my DVD collection to the share, I ripped only the movie, AC3 track, and english subtitles. Everything else was removed.
There were only a few DVDs I couldn't do this to, like concert DVDs. And, those can take a while to get started.
But, once the menu is gone, the movie playback starts just as fast as an XVID or MKV
Oh, and my storage system is RAID5 running on FreeBSD with no authentication.. So, I really don't think MS is to blame in this case, unfortunately.

Again, I was just wanting to make sure it wasn't just me.

OK... an important breakthrough...
It seems that the issue only happens the 1st time you watch an ISO. Subsequent viewings of the same ISO INSTANTLY loads the main menu and lets you quickly proceed to watching the disc.
So... does XBMC build a "cache" of sorts for DVDs you watch to speed future viewings?

Yes, I already reported this aspect of the behavior. guess you missed that part....
and yes XBMC does build a cache....

will do logs later today. very confident of the behavior. seen on 09.04.1 with 3 different OS's but most noticeable on OSX.
