cccam 2.21 is the latest. I would recommend 2.14 though. Image wise I would strongly recommend the latest VIX image. 160gb will only get you about 20 odd hours of HD recording.
I will look to dl that and was going to have a quick play about with the stock image and initialize the hdd(as i have read some poeple have had some problems) but then stick on the newest vix one.
