is there any way of uploading a channel list to my pc and then just loading the same list onto every box?
Yes , You can upload a channel dump file from your SV to your PC and then upload it back to another SV b0xes and you will have the same channels in the order you want , You will need to download the software called GT ROM Loader , it can be found in the link at the bottom of my posts marked "Eamos Library" and it can be found in the "Starvi*w/Software folder" CREATE A CHANNEL DUMP Connect the SV to the PC and put it on stand-by Open GT ROM LOADER Click "Channel Data File" Click "UPLOAD" and NAME and LOCATE the channel dump you want to save to your PC , Click SAVE Wait till you see the pop up b0x "Download Complete" before disconnecting TRANSFER CHANNEL DUMP Connect the SV to the PC and put it on stand-by Open GT ROM LOADER Click "Channel Data File" Click "BIN File" and locate the channel dump you just created to your PC Then click on "Download" and the channels should transfer to your b0x Wait till you see the pop up b0x "Download Complete" before disconnecting Connect the SV back to the TV and see if you have it now
