How to get my Amiga read DVD

xboxown · 20 February 2019, 17:14

I am using an Amiga 500 and I have Lite-ON DVD-ROM and it can only read CD's but not DVD's. The DVD is working full functional and it can read DVD if hooked into the PC but on my A500 it can only read CD's.

I am using CD2 mount in the mount list...how do I modify it so it can read both DVD's and CD's?

Thanks in advance.

DVD needs a different filesystem or drivers I think.

Isn't this something that can be resolved by modifying the mountlist icon in the devs folder?

No, DVD-ROMs usually use a different filesystem (UDF) to standard CD-ROMs (ISO9660). AllegroCDFS is supposed to support UDF, but I can't verify that. If you have a DVD that was created using ISO9660 instead of UDF, you should be able to read it with a normal CD filesystem, as essentially then it's just a big CD-ROM. ISO9660 (the standard CD filesystem) is limited to 4GB, whereas DVDs can hold closer to 5GB, or nearly 9GB in dual-layer format, so to use all the space on a DVD, CD filesystems are useless.

What kind of DVD do you try to read? Normally any DVD with an ISO9660 file system can be read just fine. UDF is not supported by any Amiga driver (even if there is one which claims so).

Normal 4.7 GB ones!

I am going to do some experiments when I go home.

Not totally sure which driver I'm using on my A4000, but it was able to read DVD Movies ok, and also play them to an extent with AMP2.

How did you get it working?

Honestly it's the same one I've had forever, I just saw the player said it had DVD support and I mounted the drive and put a DVD in it. Then I got my CD0 icon that had VIDEO_TS and the usual dirs you'd see for a DVD. It is a SCSI DVD drive if that somehow matters.

Then so be it! Today I am going to have fun and see what I get! - nods - WAIT

STOP

YOU SAID YOU HAD THE CD0 THAT HAD THE VIDEO_TS AND THE USUAL DIRS YOU'D SEE FOR A DVD.

CAN YOU PLEASE PRINT OUT THE CONTENT OF YOUR CD0??!

davideo · 21 February 2019, 00:30

@xboxown

VIDEO_TS is a standard directory on DVDs.

I doubt it was in the CD0 icon info

It's nothing special, but here it is. Disk Info shows up as 5.5GB Handler:{what you see below}CD01

DVDs if created with a UDF/ISO standard can be mounted and run on AmigaOS, of course amigaos slowly shows the videos, see screenshots and video:

I'm not sure what you mean, but my DVD drive reads at 4591KB/s with RSCP, which would be something like a 4X DVD rate, which is probably correct. Or maybe you're talking about how to master an ISO to read on the Amiga?

AMIGASYSTEM · 21 February 2019, 02:01

I'm talking about the DVD management, as you can see from the second screenshot, i mounted a DVD "UDF" (burn UDF/ISO)

Sorry I'm even more confused now. If you're talking about mounting virtual ISOs I use that one on Aminet, not sure if it supports DVDs though.

*EDIT* Oh I get it now, you're talking about mounting stuff in WinUAE. Xbone is talking about his beloved A500.

Nothing changes, I did not use the automatic mount of WinUAE, to mount the DVD I used a mountlist "CD0" with Filesystem AsimCDFS, watch the video well. I have not mounted an ISO but a real DVD

Thanks! I just have one question to ask. If I paste you the content of my CD2.info here would you confirm to me that it supports DVD as well?

Thanks in advance.

Try your mountlist and your device!

Attention, please:

DVD UDF= "Not" You can mount them

DVD UDF/ISO = You can mount them
DVD-ROM (ISO) = You can mount them
DVD-Video = You can mount them
