Fraz1:ok, thanks for that. So i can just stick a memory stick in my laptop. download onto it and then connect it to the usb port on my pvr and its sorted? Sorry if i want the idiots guide but although i use my laptop regularly i have nnever used a memory stick before.You shouldn't need to tbh, updates for PVRs are usually broadcast OTA before they're made available on manufacturers websites, so provided automatic updates are enabled in the STB's menu you'll get them automatically-Its usually also the easiest and safest method of upgrading.
The procedure for upgrading f/w manually varies from one manufacturer to another, and can be risky.
