This is getting a bit OT but I use SageTV as my HTPC based PVR. There is a brilliant plugin for this called SageRecordingExtender(SRE) which was written by a Canadian who goes by the name of Slugger. It monitors web sites like ESPN.com and will keep extending a recording to ensure that you don't miss a game because it goes overtime. This works for NHL, NBA, NFL, MLB and NCAA Football and Basketball. This has been extraordinarily useful for me.
