I am a firewire user and I am thinking of changing to using external
capture off of the component output of the cable box. IMHO this is the
only way to access all the content you pay for with cable. I have, in
the past, used a HDHomerun and while it was stable, not all channels
were available and there is absolutely no mapping of HDHR channels to
cable channels so you have to figure it out yourself. My current setup
is direct firewire capture and it also has issues. Namely, occasional
failures to capture a recording even on clear channels. This requires a
power cycle of the cable box to fix (front panel button). It always
changes the channel correctly using the firewire so I am going to
continue to use the firewire to change channels. If that fails to be
reliable, I have an older MyBlaster IR blaster I can use to control the box.
I am not up on the current products but if it captures from component
and supports full 1080i/p then its probably a good choice. I would
prefer one that is self contained and connects to the network rather
than a pci card. This is to keep the bus loading down on the front/backend.
