Ron,

You would need to scan in QAM (no CableCard) mode, but I thought with a
CableCard it would be just like adding a Firewire tuner.  There is no
scanning involved there, unless there is something going on under the hood
without intervention.

My guess is that you are actually modifying MythTV code instead of using the
Import Recorder.  If you are modifying code and are willing to share, how
would one use your code, but continue to get fixes?


It is kinda funny, because just days before your first post, I was
considering purchasing a card to try this.  My plan was something like this:

1) Use .24-fixes since it is stable and I can use a normal Mythbuntu distro.

2) Add four import recorders, one for each tuner.
- Not sure what to specify for filename.  Either use a consistent filename
for each tuner and rename later or give the filename later.  I have to
figure out how this works.

3) Use my existing video source from my old Firewire lineup.
- Since I have Comcast, this is pretty much everything but premiums.

4) Use MythTV system events to trigger the start and stop of recordings and
possibly change channels.
- I would modify the instructions from Ceton on how to do this.
- I am not sure how to change channel or which system event signifies this.

5) Allow MythTV to take care of building the seek table and comm flagging.

I may be grossly uneducated about how this works and may have poor
assumptions.
