This message is to warn you that the current Comskip can not process recordings from PC cards that record directly into a Transport Stream.
Comskip can process digital TV received by a cable or other box if it is recorded through a analog video encoder saving the encoded video in a Program Stream.
Most HW MPEG video encoder and analog TV cards do record in a MPEG Program Stream.
Also if your DVB or ATSC card can be switched to record in Program Stream Comskips is able to process the resulting recording.
