Thought this problem may be related to a virus / rootkit, so I posted in the security area and was kindly helped by that department and all test showed my systems ok

So it must be something else common....

For the past 3 or 4 years I have been trying to get a DJ video system up and running, I previously have purchased Hi spec motherboards, rapster harddrives, a range of powerful graphics cards etc.

I have never been happy with the video output whilst playing vob video files from my hard drives after ripping the files from my Music video DVD's

they always played choppy and jerky from the hard drive on ALL my pc's, (this is where I keep moaning about all my systems having performance issues!!)

I have also tried a range of ATI and Nvidia video Cards

So a month ago I purchased a top spec Intel I7 system 6gigs of DDR3 etc, etc, so no one could say my hardware was under spec.

When I played my ripped vob video files on the new system bang still choppy playback and this is on every pc I have Win7/XP

The issues seem more visual with NTSC video files (29 frames)

So I contacted a video company in the uk this week who transfer video formats as a service and spoke to a gentleman about my problems

I sent him the VOB video file that plays Jerky & Choppy on every machine here, he tried it on his vista machine and he tells me it plays perfect. ??

Point 1) I know its Not my Ripp as it played ok on another totally isolatted PC (I use DVD decrypter to rip my vob files)

Point 2) It does not matter what PC here I try it on, It plays Jerky / choppy

Point 3) When ever previously I try and do any multimedia work, slide shows, video etc. I always seem to have problems ??

Point 4) I have tried installing lots of different codec packs all with no joy

I then tried another test,

after ripping in my madonna DVD to vob files again this DVD was again was in a NTSC format, the files of the harddrive play jerky & choppy

So I then tried to put the modonna DVD in my DVD drive and played the same track that I had ripped to my hard drive that played jerky !!

It played perfect from the original DVD in the DVD drive ??? no jerky playback... so what different ?? it a read only file on the DVD !! NOT playing from my hard drives....

So what we have here is......

1) My video files play perfect on someone elses system
2) My video files DO NOT play perfect on any of my machines !
3) Yet if I play from the original DVD it plays ok ?? (READ ONLY FILES !!!, can not be written) maybe a big clue !!!

It seems that when I try to play any NTSC files its jerky and choppy when played back on any computer

My end result is to use virtual dj software to play them on my crt monitors, but they play jerky on the monitors, so first off it would be good to get these ntsc video files to play correct and smoothly in windows first.

I have tried both windows media player in windows 7 and VLC player

Please can anyone help me

Thanks in advance if anyone can shine any light....

when you are playing a file whether it be from a read only dvd or a file on your hard drive the media is not being written to it is only being read.
you said your playback is choppy across all your computers but not the computer that you sent the file to.
there is your difference.
find out what program the specialist used for playback
how did you send the file to the specialist?

if you are getting poor playback from a rip it is usually due to a bad rip, low frame rates or poor processing but you said that the specialist could playback fine so you have to find out why he could play it and you can't.

it could be due to the file being fragmented on the harddrive,

try defragging
