View Full Version : Patching aspect ratio in home recorded DVDs...

I've been puzzled a little bit with something I've tried to do in terms of altering the recorded aspect ratio in (well really with the contents of) a DVD (RW) I recorded on my standalone recorder.

My recorder only records with aspect flagged as 4:3 (although does record all anamorphic recordings with all the picture), I can change my viewing settings on the TV for anamorphic widescreen stuff that I've recorded, so that it displays correctly.

On playback, my recorder normally honours the aspect ratio on DVDs - certainly does with commercial DVDs, and also with DVDs I've authored from captured material (ie stuff I've spooled off my PVR using a Hauppauge PVR-USB2, then edited to remove adverts, and then authored to a DVDR).

Anyway, I'd recorded a TV program on my DVD recorder, that's broadcast in anamorphic widescreen, to a RW disk. I then ripped the contents (well I say ripped - it's domestic DVD recorder, so there's no encryption or protection), then used DVDpatcher on all the VOBs to simply switch the aspect ratio from 4:3 to 16:9. I did that for all packets, not just the header, and on all VOBs.

When I playback on my PC, using VLC, everything is correctly displayed as anamorphic widescreen. So I use imgburn to burn this back to the RW disk. Play that on my PC using VLC again, and it's correctly displayed as anamorphic widescreen.

When I take the disk and play it on my standalone, it plays it as 4:3 and doesn't switch to widescreen as it normally would.

What am I missing - how else is my standalone inferring the aspect ratio - because as I said, it's always been spot on previously, both on my own authored DVDs, and commercial copies.

Thanks for any tips.

A dvdplayer has to read the AR from the Ifo - patching the VOB does not alter the Ifo

Open the DVD with Pgcedit (http://www.videohelp.com/~r0lz/pgcedit/pgcedit_winexe.zip) and mark the movie in left pane, from the top menu choose Domain - Domain Streams Attributes
Set to 16:9
Save DVD

Many thanks, much appreciated - that was it.

Try http://www.svcd2dvd.com/Software/IfoAR2WS.aspx ... I had the exact same issue as you. As bigotti5 said the VOBs will already be 16:9 so they can be left alone.

although... some DVD players will actually read from the stream as well as the ifo. god knows why.

it's probably worth changing aspect ratio in both the stream and the ifo.
