Title: increase buffering for files on NAS?
Post by: Osho on May 10, 2007, 12:33:15 pm
Hi,

I sometimes have trouble with playing files on NAS due to wireless performance issues. Particularly for DVDs ripped in full resolution. I have so many jitters and pauses that it ruins the experience of watching movies. I was wondering if it would be possible to increase buffering for all files residing on NAS?

thanks,
Osho

I'll second that. I'm experiencing the same thing with hd trailers that I've downloaded and try to play over my wi-fi network.

I believe most wireless is half duplex, this means for the ack packet to get sent back to the originator the wap has to switch from transmit to receive which takes a discrete amount of time (this may not still be the case but I think it is). Buffering may (or may not) help this.

I assume that it works fine if you don't use wireless.. Are you running at 54mbps?

My router is ".n draft 1", but my client pc is only "g". I have managed to minimze the jittery playback if HD a little by setting a specific channel on the router and playing with it's antenna to maximize the signal strength on the client pc.

I wonder if MC stops doing background tasks during video playback or not. Thumbnail building, checking/downloading podcasts etc. could all take up valuable bandwidth. How does MC work in this regard?

I replaced my g router with 802.11n draft router.. I also replaced the card in PC - but I still had issues with the connection loss. It was much better though but still every once in a while (partiularly while using microwave or cordless phone - both of which run on 2.4GHz band) - I will experience jitter/hick-ups.

thanks,

Some phones run at 5.8.  I don't know whether that would help.

That's strange because I am able to play VIDEO_TS dvds fine on my wireless g network.  And it usually runs at less than 54 Mb because I'm too far away.  If I'm not mistaken, DVDs are running at around 8Mb/sec so you've got 48 Mb or so!  That's six times the data rate required.

It does, quite often.  We replaced our 3-4 cordless phones at the office with 5.8GHz models, and amazingly the wireless network reliability skyrocketed.  Of course, we're using very high quality WAPs (http://www.cisco.com/en/US/products/ps6306/index.html).

I loved an experience I had at Radio Shack quite a few months back.  We were buying a cordless phone on the 900 MHz frequency and somehow, the guy (no idea why) was really pushing for a 2.4 GHz model and saying it was so much better.  I just told him that our 900 MHz phones work fine and our wireless network is very important.  He would not let up--oh, it won't interfere, blah blah blah!  I know huge issues that can arise.  It was a horribly confusing experience that the employee just seemed utterly confused and flustered...only to present dead silence when I finally proved him wrong.  He just would not give up.

Yes but no microwave runs on 5GHz!

Could you please tell me what DVD filter are you using ? Maybe it has something to do with which filters I use..
