If you don't need analog then that makes things considerably simpler. The tuner will already deliver MPEG-2 (since that's what the broadcaster is sending), and tuners can be configured to deliver a full stream for cases where there are multiple channels on the same frequency. That said though, you are limited by the number of physical tuners in that a single tuner can only be on one frequency at a time. What you need to understand is that different products have different numbers of tuners. For example, the Hauppauge HVR-950q has a single tuner which can be shared for analog and digital while the HVR-2250 has two tuners (each of which can tune to a single analog or digital channel). There is no inherent limitation under Linux which prevents you from having multiple tuners in use in parallel. In fact it's actually quite common (many MythTV users for example record several programs at the same time since they have multiple tuners installed). Devin -- Devin J.
