Why wont my tivo record these shows?

i set these shows to record on my tivo ghost whisperer, whose line is it anyway, family guy, neds declassified, law and order svu, law and order. and i set family guy and ghost whisperer to record all the episodes. both shows are on every day and whenever i get home from school to watch the episodes that were supposed to be recorded, law and order records instead. and family guy just wont record at all. nobody is here to change the channel for family guy and ghost whisperer has three thumbs up and i pressed set all episodes to record but there not recording. plez help me to figure out why there not recording. thx
