How to sort jerky DVD replay?

Hi,

Just installed a new HIS AGP 3850 card, but seem to be suffering jerky DVD replay with VLC and Windows Media player?

Codec issue?

Using an AMD Sempron 3300 single core CPU (same as the Athlon XP 3200+ with 400mhz FSB and 512K at 2.2G, plus 2G of XMS 3200 currently running at 2/2/2/6 and 233.3mhz with 2.5v.

Windows XP Pro with Service Pack 3.

Any tips on getting smooth DVD replay?

my guess would be either a coded issue, or the DVD drive running in PIO mode (thus not transfering the data fast enough).

Hi,

I'm not that clued up, what is Pio mode?

Ta,

Ok found that out, tried DMA if applicable but no change?

Rubbish DVD drive? I am sure I have read of people using old processors for DVD replay?

Windows Media player is smoother than VLC but seems more washed out and greyer with blurred motion? on faces and such, which is not an issue with VLC which is far crisper and more natural with good contrast but very jerky playback?

does it show the DVD drive as running DMA mode x? (I can't remember if it's under the drives properties or the controllers).

You can get perfectly fine DVD playback with very low end CPU's (sub 1ghz, sub 500mhz if the videocard is any good).

It might be worth updating the videocard drivers, and checking the settings in the ATI control panel, as that card should be more than fine even on a very low end system for DVD playback.

Hi,

With downloaded HD 720 content I get getting good results, with 1080 downloads its jerky.

DVD after playing with settings is slightly better but still some artefacts, and at the moment I am playing with S-Video out but not getting a true widescreen display with the DVD drive replay, but its fine with most of the HD content downloads?

I do not have any DVD's on my Hard Drive so I am only playing them via the Lite-On IDE DVD drive.

To change to DMA mode from PIO... I've always found you need to change it in Windows (as you've tried)... Reboot... Remove (Uninstall) the IDE channel the DVD is sitting on from 'Device Mangler'... reboot

Windows should then re-install the channel in DMA mode no problems!!...

Worked for me each time I've had to do it!.

Did you uninstall previous/old GFXs drivers before installing new card & drivers?

Did you have another card before or onboard? Either way they should have been some sort of drivers installed.

Hi,

Still not getting smooth DVD replay, nor able to find any old graphics drivers, old cards were an ATI Radeon 8500LE and nVidea GeForce FX 5200.

My old Mac G4 is giving me better DVD replay!

yes, a device mangler can usually be an issue.

Stating the obvious here, but have you tried playing back the DVD in a DVD player (stand alone) or a different DVD drive? *edit - sorry read through*

Cheap discs, along with a bad burn will cause skips. Usually jerks and skips I would blame on the optics. I would try a different drive in the computer and see if you've a bad one. Should a different drive fail to play movies in your computer still, I would blame it on IDE/mobo stuff, then codecs/drivers.
