Jerky playback on DVD

[m.birtles]

Have just changed the DVD/CD drive in Acer Aspire 3023 Laptop.
Have put in a Sony drive but when I try and play DVD it is jerky.
Why would this be ?

Have solved the problem. Uninstalled the Secondary IDE Channel from the IDE/ATA ATAPI Controllers in the Device Manager. Then re-booted. Windows re-installed the necessary drivers and voila.
The driver advanced setting was set to 'PIO Only' instead of 'DMA if available'.

Why didn't you just buy a new laptop?

If I was going to buy a new laptop then we wouldn't all (for example) be needing a site like this would we (smart alec) !

what chipset is it? manuf's drivers are much better than generic ms ones.
youcould have changed the setting manually, tho god knows why it sometimes defaults to PIO, I didnt give that a thought tbh.

If memory serves, Windows can sometimes do an automated 'fallback' to PIO mode if it has had problems reading a CD/DVD (e.g. scratched/dirty). There maybe some obscure article you can find on the MS website that discusses this.
