Tweaking Comskip
Depending on which PVR option you use, fast forwarding thru commercials or skipping them altogether can be a huge hassle. Unfortunately, tools for routing around this problem remain scarce. Assuming your PVR solution records in MPEG-2, one option is the rather convoluted paring of Comskip and Comclean. Comskip is a command line tool to detect commercials in MPEG-2 video while Comclean is a companion tool for removing the detected commercials. With some careful reading of the directions you can get the process down to a science, but this is definitely not meant for the casual user. [Windows 9x/2k/XP $0.00]
