Hello,
1. I`ve had a DVD drive in my Amiga for approx 1 year now. The Allegro filesystem provided with the PowerFlyer IDE cards handles them fine. I only have an 060 however, so I can`t comment on how fast a PPC could play DVDs.
2. As filson said, if you have more than one computer, you should be able to get online with an ethernet router (approx £40), however most of these require a seperate ADSL Ethernet modem (approx £60). Netgear have one with both built in for about £115.
If you are using Genesis/AmiTCP on you Amiga, you will NOT be able to use DHCP. Genesis/AmiTCP only support BootP (an earlier version of DHCP), which doesn`t support all of the required info.
All is not lost however, configure your IP address manually, set you Default Gateway as the IP address of the router (not the modem!), you`ll then have to configure your ISP`s DNS servers manually.
I have been using this for just over a week, with no problems.
Regards,
Frank.
