Dear Friends,
is it possible DVD watching using an Amiga 1200 classic?
Thanks, Carlo

Nope. Not enough horsepower.
If you've got a PPC, then maybe. I'm not even sure there is DVD playback software for OS3.x

No. However, if you convert the DVD to an .AVI or Mpeg file on the PC and then transfer the file to the A1200 (you could burn it to a CD or DVD) then you oculd use FFplay orother AVI player to play it back on the A1200. It'll be a very small screen though.
I've done this on my A4000 but tis got a RTG and Cyberstorm MKII in it.

You should be able to on a 040@25mhz or better. I have played MPEG 2 files without issue though not an actual DVD.

Best option for classic users to play videos with is probably FroggerNG. Has best support for classics and is much faster than things like FFplay. With a bppc and rtg an a1200 using FroggerNG is more than capable of watching mpegs full speed and can even watch divx files as long as the resolution of encoded video files isnt much higher than something like 320x240. It's far from great, but I think people might be pleasantly surprised at the results obtainable, even on an '060.

As others have said, straight from dvd no dice unless you upgrade. Even if you convert to mpeg, I doubt the 020 will have enough juice to play it.
On a somewhat related subject, here is a C64 playing Star Trek.

Is there a story behind this?

Yeah, inquiring minds want to know. Looks like a C64 emulator running on a powerful PC or something. I saw a pointer though that looked like an Amiga style pointer...

a few years ago i used a program amigaamp (i think) it was a PPC program i used on a Blizzard PPC 270Mhz. this blizzard had a very fast bus speed with memory setting set on the card set to no-read/write waitstate and so in the memory config everything turned off.
playing DVD was almost perfect it skiped about every 2-3 seconds using a SCSI DVD rom 10x.
but things have moved on and things have improved a lot and now it's 320MHz or 322Mhz with 80MHz bus. this new speed may get rid of some or maybe all of the skipping. the PCI has also gone up in speed from 25Mhz to 35Mhz. so if i have time i will set-up my old 3.9 system and test again,but i think it's all going to come down to how the SCSI works at this new speed if it shows any errors.

Not likely (040@25MHz, I mean), at least not at the proper resolution/framerate. First of all, the resolution of DVD rules out playback on most m68K amigas. A PAL 720x576 @25fps using (where supported) a packed 24-bit RGB framebuffer needs 29.7MB/s VRAM write speed to keep up. On a 32-bit framebuffer that increases to 39.55 MB/s.
So, even assuming you go for 16-bit RGB565, you are talking about 19MB/s which is more than you can get transferring data to the BVision using an unrolled move16 loop on the 68040 (the 68060, however, can move data a bit faster than the 040). Every other Gfx card available for the A1200 has a slower CPU -> VRAM path than the BVision/GRexx does, especially Mediator attached cards.
You'd literally use up virtually all your CPU power just updating the display, without even worrying about decoding and CPU hungry disk IO if you are using a non-DMA DVD drive.
I've played back (non-CSS) MPEG2 streams from hard disk on the PPC to BVision and that's worked reasonably well, albeit at a slightly lower resolution than standard DVD. Playback of actual DVD disks read via DMA would seem reasonable on that premise.

delshay you must have a laboratory dedicated solely for close examination of Blizzard ppc's :D

It's Wings OS for commodore64. Multitasking 16 bit OS with irc client, tcp/ip stack, video player, music player, browser, image viewers, etc, etc. Requires both scpu expansion and something like Ramlink and IDE64 (essentially c64 upgraded with faster cpu, more ram and ide interface(ergo hdd/cdrom)). It's my most wanted retro toy in the world, have wanted to play with Wings for years, but unfortunately the hardware isnt common and not cheap either. Very cool stuff though :-)

Wow! What sort of setup is that?

is always very nice to read comments so competent!!! :)
Amiga.org is a great place with great people!!
