1) this should be in n00b section
2) DSR = Direct Source Rip (i think) which means they rip it from the source either firewire on cable box or a DVB card, it is of lower resolution than PDTV. DSR, PDTV and HDTV are ALL direct rips which will give best quality.
a reguar analogue rip via svideo is just TVRip
