replay dvd's quality

[david4]

Not sure were to post, if am in the wrong site please redirect me.
I use a program to backup my legally purchased DVD movies trying to build my collection on HD's for replay.
When I backup those movies to my HD, noticed instead of one single file the movie is divided/split into several video files of different lenghts.
To replay the movie I have to play each file separated, like if several independent movies.
Also the quality on replay is degraded as well as the speed, withjerking and freezin frames.
However if the same folder is burned to a DVD, it plays just fine as the original.
Is almos like the recording to the HD scaters the files.
What do I need to do to correct this.
thank you very much.
PS
I tried different movie players no difference

what are the specs of your computer? IE cpu, graphics chip, hard drive

Your backup program is splitting the content to fit onto 4.7 GB discs, and is compressing the content in order to do so. Disable those options and do a 1:1 copy instead.

I think he is talking about .vob files. Depending on media player and its configuration, the quality will vary. I don't think hardware has much to do with that.

Are you playing both the disc and the .vob's on a PC using a same media player?

thank you for all replies.
Sys is a EMachine
Intel CeleronD 330 2.66 GH WinXP home edition SP3
256 L2 Cache
2 GB Ram
Jaton Video Card PCI Video Card 64 DDR MX 400
Software used is DVDFAB6
I agree it seems related to the software used
The image created is NOT compressed
the DVD player is always the same

I should clarify this, the DVD player is the same for the PC, when playing the recording from the HD, the DVD the DVD is played on a regular external DVD player with no PC connection and thru the home theater system

As far as the quality/jerky playback, if you're trying to play it at upscaled resolution your PC is way out of date for the task

 

[david4]

Thank you
Now independent of the quality, why the playback does not integrate the video into one single show and have to play each individual file as a free standing??

 

[yh125d]

Because that's the format DVD videos, with the video_ts VOB bullcrap. That's just the way it is. What I do for DVD's is just rip it as an image instead of as a video disk, then use daemontools to "mount" the image and playback normally

 

[david4]

OK there is the why, well that makes sense, will have to look for that daemontools then, thank you very much.
