Setting a timer from guide or as to record on that ONE channel only will save memory, and we use a WHOLE LOT of timers and events in memory, so we need to be as efficient as possible. Many parents with kids have found the Dish Pass and Seek & Record hell with those timers for those kiddie shows that air 20 times on one channel, another 20 times on the West Coast channel and another 30 times on a different channel. Unless you have only a few timers, use Seek & Record only when you want or need its advantages.
