I take it that the VM supplied splitter for the set-top-box and cable modem is just a resistive splitter and does not contain any RF components such as high/low pass filters as used with ADSL. Also, VM specify which socket on the filter should go to the STB and which should go to the CM. Does this imply that the splitter is asymmetric (i.e. different resistance on once side from the other)?

Basically, when I installed my cable modem recently I put the VM splitter in first and fed the STB side to my existing four way (yes 4-way!) splitter. The CM worked fine but the STB couldn't hold onto the signal. If I could do away with the VM splitter and feed the CM from my own without degrading the broadband signal that would be great. Alternatively, I could just get a smaller filter as I don't really need all four outputs.
