My aunt has a P2-600 MHZ comp with 128 megs of ram. She has not been able to burn a DVD on her 8x external Sony DVD burner. Is it even possible with that slow of a computer?
with external burner I would say not likely. everything is slow cpu usb bus.
time for a upgrade. I cant imagine how long encoding would take on a system like that,
Definitely not on a USB 1.0 - only 12 Mbps, which is about 1.5 MB/s, and DVD 1x is around 1.3 MB/s, plus USB is never 100% at its full speed (firewire is better at sustaining speeds).
With even just a modest bump in the comp's power external DVD burning would work fine. I recommended a friend of mine an NEC burner with an external enclosure and her notebook at the time was a Pentium 3 1 Ghz (or so), with 256 MB of RAM, but she had USB 2.0 and she got successful burns. But with a Pentium 2 (did they even make a 600 Mhz PII? I don't think so) - no, plain and simple.
Now I think she uses a G4 ibook (no idea about the speed) and seems to work fine too.
