I have an external USB 2.0 Freecom Classic DVD+/-RW which I run on a desktop through a USB 1.1 connection with Windows 2000, P4 1.5Ghz with 256Mb RAM, Nvidia TNT64 32mb Graphics Card and Realtek AC97 Soundcard.
Using the free RoxioDVD player bundled the playback is always jerky (sound and video). When I first got the player I played a DVD and everything seemed fine.
I have connected to my laptop running XP and USB 2.0 with P4 2.8Ghz 512Mb RAM and integrated graphics and sound card. The DVD playback with the same software runs fine on this although I have just run it again and looked at the Task Manager which even on the laptop was showing between 90-100% CPU usage!
Is this a software problem or hardware issue? I flashed the firmware on the Freecom Classic and had to return it for replacement, so would hope to find a solution that did not involve updating the firmware.
The only other thing I can think of is that I connect via USB 1.1 but I don't think this is the real issue.
I have tried the Freecom Tech support with poor response i.e none so far!!
Try Windows Media Player. It might work as you have the Roxio software installed. Your graphics card should be ok but check for newer drivers. I run an old IBM laptop and a Dell desktop and both plat DVD's no problem. I think the laptop has 8 mb built in graphics memory with a Pentium111 1 gig and the Dell a 32 mb card with a Pentium111 700. As Woodchip says though an external DVD Rom isn't the best idea for watching DVD's.
