On my G4 Mac mini which I am using as a media centre under my television I have an EyeTV USB Freeview device for watching, pausing, rewinding and of course recording live television. I have been having a few issues with the quality of the recordings and viewing live television in terms of interference, but also when watching if a live TV window is open. I suspect that part of the problem is the speed of the G4 which is rather slow for a Mac and it only has 512MB of RAM.
I am wondering if I use the EyeTV 410 which is connected to my iMac whether that would make a difference? Whereas the EyeTV USB device is dependent a lot on the Mac for processing the video, the Firewire 410 device has a hardware encoder which in theory takes a lot of the load of video processing off the Mac.
I might give it a go and see how it works out, but will leave it till later as the iMac is going to record the final episode of Robin Hood tonight on BBC One.
