by KennyR on 2003/11/1 17:51:12 The data transfer rate you need for DVD is huge. It's like 30MB/s or something. There's absolutely no way you can get this on an Amiga, even if you had the CPU power to decode what you got back - which you don't.


Normal DVDs dont exceed 1.5 MB/s

Dont start with this one, I create DVD's my self (Its my job) believe me i know!,

mikeymike:He's right you know. 10MBit/sec.

DVD playback poses two types of system stress: Reading at a guaranteed, sustained 10MBit/sec and decoding the contents coming off it quickly enough. The system must be generally (as in, lack of bottlenecks) fast enough for one operation not to negatively affect the other


Yes 10MBit/sec (MebaBits) will give you about 1,25 MB/sec (Megabyte/second). It is about 1.5MB/sec i pointed.

I really dont know if amiga is capable of playing back MPEG2 but as for the transfer rate I am definately sure that is 1.5 MB/sec :-)

KennyR Edit: Actually, you could be right. But it's not just the transfer rate, it's the CPU load. PIO controllers like Amiga IDE or most of its SCSI solutions eat almost all CPU time at full transfer.


KennyR, I didn't mean to offend you.
DVDs use about 1.5MB/sec and thats final.
I just wanted to correct something that might have put the conversation way out. :-)
