Different kind of VOBs?

[Teresa Lam]

I've ripped a DVD and have a number of VTS_02_n.VOB.
I copied these VOBs to my HDD Media Player (KL-GS063A) to be played.
I found that for some of the VOBs, the audio track is gone. (When I play the same VOB on my computer / DVD player, the audio was fine)

My HDD player seemed to distinguish different kinds of VOB, with "File Viewer" mode, I can see that for those VOB with audio, my HDD player indicate it as a "DVD" type file (there is an icon indicating its type, please refer to jpg attached).
For those VOB withOUT audio, they were indicated as "MPG2".

Can someone explain the 2 different type of VOB despite they have the same .VOB extension?

One more strange thing is that even if I change the file extension from .VOB to something else, my HDD player still recognise them as playable videos!! So the extension doesn't really matter to my HDD player !?!?!

Thanks!

VOBs aren't meant to be played. Thats why you get strange playback. A vob file can contain several audio tracks and also subtitles and still images so the player may have problem select what to choose.

I guess that your player don't support real dvd playback from the harddrive(open for example video_ts.ifo or video_ts folder and play the dvd with menus and such). Then you can try rip out other audio tracks and subtitles using for example dvd shrink and then make one mpg file with vob2mpg.

Hi Baldrick,

thanks for the reply, you're right my HDD player said it support DVD but didn't really

Quite sure the HDD player didn't read the IFO, cause when I play the video, it cannot show the subtitles. The HDD player was just scanning all VOB available, display them as thumbnail, when you choose one of them, it just play the VOB as such, so some does not have audio

Given the limitation, I'm now merging the VOBs into one big one (i.e. multiple chapters of one movie onto one big VoB), and I can play the whole thing with audio

By the way, do you know a way to embedded the subtitle onto the VOB file?? so that I don't need the IFO?

Thanks!
