Try play with MPC first, press SHIFT + F10 and copy the media info text and past here, most new lappy can play bluray video without the problem, but culprit is, you never know the encoder used what compression option during transcoding, like Hi10p + 16 reference frames, such video does not work with Dxva and will cause playback become sluggish because cpu struggling to decode it at real time.

QUOTE(abubin @ Nov 10 2013, 12:06 AM) First thing that you need to do is to find out whether the problem is with playing videos from USB or the USB HDD itself giving problem. Once you narrow down the problem then only you find solution to it. He mentioned its USB3 with 90Mb/s speed(equal to 720mbps, bluray max data rate is 36-54mbps), its more than enough to play bluray without keep buffering.Try to transfer the video and play directly in your lappy. Does it lag in this way? When transferring a big file to your lappy, does the transfer lag as well?  Either codec related or poorly muxed video.

QUOTE(abubin @ Nov 10 2013, 10:45 PM) transfer rate is 90mb/s but is it consistent? Still, does the video jerks when played directly from local hdd? These still need to be tested to be conclusive. A good technical support does not make unnecessary assumptions. Well, you do have a point, but even USB2.0 Bandwidth is already more than enough to playback bluray video smoothly, it's impossible for Harddisk on USB3 become jerky, Unless the harddisk is dying, bad sector will affect data transfer date, and the video will become corrupted, ended abruptly, or visual artifacts will appear, which TS didnt mention any.I always play my video from my low end HTPC which both are connected to GBE lan port(is slower than USB3), i never encountering any issue because i know how to configure my video player setups. My guess is still codec/splitter related problems. |

QUOTE(SpikeTwo @ Nov 11 2013, 08:47 AM) the external hdd is a new one. the sngle large file transfer speed is consistent 80-90mb/s while many smaller files would drop the speed to 40-50mb/s. I havent really test the movie full run, only played it like 10-20 mins from lappie HDD, seems ok so far. cant really conclude yet as the movie stutter occurs intermittently. will get more to that when I'm off work. i have updated to latest intel usb3 driver instead of using the microsoft win8 ones because I cant flash my phone with microsfot drivers. Not Hi10p 1080p, yup do not let other software utilize too much cpu time, it will cause your video playback stuttering, unless your video playback is accelerated by GPU/Dxva. any idea that mcafee real time scan might be the culprit? i will also try to disable it while watching movie tonight. here's the media info: » Click to show Spoiler - click again to hide... « |
