Jerky DVD with Videoplus 10

Hi

I'm experiencing jerky video playback on DVDs created with Videoplus 10. Have checked other posts and have ensured project properties and create DVD properties are both set to Lower Field First.

The strange thing is that if I create a Video File with the same properties as the project properties and use Nero to create the DVD then there is no problem.

Source files created on mini DV Sony DCR-HC24E and connected via firewire.

Project Settings:
PAL (25 fps)
MPEG files
24 bits, 720 x 576, 25 fps
Lower Field First
(DVD-PAL), 4:3
Video data rate: Variable (Max. 8000 kbps)
LPCM Audio, 48000 Hz, Stereo

Output format DVD
MPEG files
24 bits, 720 x 576, 25 fps
Lower Field First
(DVD-PAL), 4:3
Video data rate: Variable (Max. 7000 kbps)
Audio data rate: 256 kbps
Dolby Digital Audio, 48 KHz, 2/0(L,R)
PAL or NTSC

Can anyone shed any light please?

Andrew

Try burning the DVD to a hard drive folder and playing it with your favourite software DVD player. This will help show if it is a problem with the DVD burner / DVD Discs rather than the software.

Thanks for the advice.

Have created a disk image as suggested and it does seem to run smoothly. Does this suggest the DVD writer is at fault?

I use an external DVD writer connected via USB 2.0 (HP dvd 840) as the internal DVD on the laptop is broken. (Getting inside a Sony Vaio is not easy and buying the external drive was considerably cheaper than sending it back to Sony for repair!) As Nero worked OK I didn't even consider it a possibility.

Is this something I will just have to put up with. I guess I can use the disk image to burn DVDs with Nero?

Hi Andrew,

Since the ISO or DVD folders (VOB) play smoothly, then I fear that the external USB DVD Drive is the problem. The USB probably is having problems keeping up with the data flow.

USB uses a Slave-Master architecture, where the computer handles all the arbitration functions and dictates data flow to, from and between peripherals. This can add to the overhead, which can cause certain data flows to slow, when you don't need or want them to.

Firewire uses an intelligent Peer-to-Peer architecture, where the peripherals can negotiate which ones can best handle the transfer of data.

Because you say NERO works OK with your machine then the easy option is the best. Burn your DVD to the Hard drive and then use Nero to copy it onto your DVD disc.

It is my normal practice to always burn to a hard drive folder first anyway - the reason is so that I can do that final check that everything works the way I wanted. It also offers an opportunity if necessary to make adjustments to the completed DVD that cannot be done by the editing/authoring programs.

Here I use MenuEdit and/or PGCEdit.

Examples:
DVD Workshop 2 and 16.9 menus - example of using PGCEDit with a Ulead product.
