Guys
Granted, we will never have the kind of programs that are available on Windows but we do have all the tools we need to get by.
I am running OS X 10.4 (Tiger) and control my 7000S and 500S no problem.
I have Dreamflash(multiboot) installed on my USB stick(7000S) and use MPEG Streamclip to load and delete new images and reformat USB stick etc. In fact this program is the nuts as it can also record direct to Mac hard drive.
I use iDreamX (version 0.7) and have no porblems whatsover with it - this I use to load my bouquets and arrange my channels. (no where near as easy to use as DreamEdit but we're never gonna get that)
Safari web browser works too and I can stream to VLC. One word of warning though - the newest version of VLC doesn't work on the streaming front - the version you want to run is 0.7.1.a.
Also a little tip for streaming (and I apologies if you guys already know this) is when you click vpid value in the Dreams web interface, this will d/load a 'video.pls' file to your desktop. Highlight the file and 'Get info' and in the drop down menu 'Open With' - select VLC. Also click 'Change All' button underneath. Then whenever you select the vpid link in the webbrowser it automatically opens VLC and streams.
Also, there is a program called ffmpegX which is the absolute bollox for converting files to different formats. So say you have a Divx file on your mac and want to watch it on your dream, ffmpegX will convert it to a .ts file. FTP it to your box and you're away.
Hope this helps guys and if you are stuck, give me a shout and I mightbe able to help.
