What factors determine how fast MBT starts a movie on one computer vs another?

Of the two computers in my house that are running MBT and accessing MBserver from a third computer (all wired to a gig E network),  my laptop starts a new movie in probably 15-20 seconds while my desktop starts it immediately. A networked Synology holds the movies.

 

The desktop is definitely a faster computer,  but the things that I thought mattered are very similar.  Both have a Core i7 and 8gb of ram.   

 

The desktop has an SSD.  Does this make the difference?  Does MBT cache data locally before playing it so maybe I am waiting on the much slower laptop hard drive to do the same?   

 

The desktop has a Geforce 780ti video card while the laptop has onboard HD 4600 graphics but I wouldnt think that would matter in this scenario.

 

The laptop is running win 8.1 pro and the desktop Win 7.

 

Both are set to 40mbps "bandwidth"  in the MBT settings.

 

Thoughts?

OK I installed an SSD in the laptop, but that made no difference,  so hard drive speed is not part of the issue.  When I opened the laptop I did find that only one 8gb dimm is installed, so it would not be taking advantage of dual memory channels.  Could that have anything to do with it? That is the only large hardware difference that I can see, other than the video card.   Nothing seems to be stressed though.

 

Perhaps its Windows 8?

I know both are wired to a Gb network, but does your laptop have a Gb Network Interface? If not, its probably pulling in data slower. Though if its an i7 I would assume it does have a Gb nic

I have an a Celeron 1.2ghz on a wireless network and videos will play instantly. Problem could be the audio settings or some codec reason

yeah its a GB nic.   Its also a fresh install of WIN 8.1 pro.  Just updates applied and MBT installed along with LAV filters.  I also installed MadVR to see if that somehow made a difference.  Predictably, it did not.   I will grab another SSD and install Win 7 on the same laptop and see what happens.

Well part of it is that I want to use the MBT interface, and the other part is that I just want to make it work.  It works great on the core2 duo / integrated Geforce 9400 PC I have that houses MB server and MBT,  and it works great on the other PC that is very powerful.  But on this Haswell PC, as well as the low powered Celeron I tried,  I get a massive delay before the movie starts.  I want to figure out why.  

 

 

I just did a clean Windows 7 install and am getting the same issue on this laptop. Crazily enough,  the MBT installation did NOT force the install of LAV filters this time, and it DID play video.  Not sure how....  Like I said, its a clean win 7 install so no filters or codecs were on the system.  I did go back and install LAV, although I am getting choppy / tearing video so trying to troubleshoot that.  I also tried my hand at installing MPC-BE but have not been able to get that external player to work.  It starts,  but no video plays.  Guess I should stick to mpc-hc since I have that working on other computers while still trying to troubleshoot this delayed start issue.  

 

So I still havent found the culprit.  Any devs have an idea?

OK I think I have figured out what was making the movies start with such a delay.  It must have something to do with the network authentication from the computer that is playing the media back to the Synology that is hosting the media.  Once I mapped a drive from the Synology to this new PC,  it all of a sudden started playing back the media immediately.  So before it must have been going through MB server for the authentication, and now its directly authenticated.  I dont even think it mattered what folder on the Synology I mapped to this pc,  just the fact that some folder using the username and password was mapped.   So there you go....

 

 

Now to troubleshoot the video.... I will start a new thread for that.
