Re: [BC] Optik TV - Install w/ Ethernet or HPNA through coax bet I agree that your not likely to run out of bandwidth on the shared HPNA network which usually runs at 120 - 144 Mbps. If your HD PVR and three STBs were all HPNA connected, the worst I could come up is roughly 36Mbps. The PVR would have to record three HD shows (3 * 6Mbps) and then play them back at the same time to the three STBs (3 * 6Mbps).
The big advantage with Cat5E is you get a dedicated 100Mbps bi-direction link to each STB. Ethernet is also easier to troubleshoot if you have one bad drop. One bad HPNA coax drop can disrupt the entire HPNA splitter and its trial and error to find the bad coax connection.
