I've noticed with TVE shows, they often lag real time by at least 1 minute (often more) so I end up using 3 minutes just in case. Choosing 3 minutes of padding at the end usually is at least a minute too much, such that when watching recordings of TV series marathons you end up watching the first minute of the next show then need to fast forward over that already watching minute when the next recording plays. Having an option to add 2 minutes of padding (rather than 1 or 3) would help fine tune this!
This is definitely a "first world" type of problem, so kudos to your software!
