The WinTV-DCR-2650 will not work with your satellite video source. The WinTV-HVR-2250 may or may not work with the analog output from your Satellite set top box. Even if it does, you will not be able to record channels in HD. The analog (COAX) output of the set top box down-converts the signal to 480i (standard definition).
There are three copy-right tags:
1) Copy-Freely - You are able to record, copy, and view recorded content on any device.
2) Copy-Once - You are only able to record and view content on the device it was recorded on.
3) Copy-Never - You are unable to record this content (usually limited to PPV and special sporting events).
These tags are entirely up to your cable/satellite provider.
Personally, I wouldn't recommend either option and just stay with the DVR available from your satellite provider (or switching to cable).
