Recently added a DVD drive to my PC (I'm a Sloth Adopter). The drive came with PowerDVD 5.0, which I installed. This software seems to work well enough, but it doesn't seem show anything more than what I see on my TV. Most DVDs with PC-based extras seem to run off disc with no installed footprint anyway (Planet of the Apes 35th). Then I played 'Harold and Kurmar' and it wanted to install the InterActual player....OK. Then I tried to play 'Scary Movie' and it wanted to install the PcFriendly player....OK. Seems like older software, but the PC-based content for 'Scare Movie' looks good. Do I need to keep all these programs? I thought PcFriendly was replaced by InterActual? Also found some web links that seem to refer to PcFriendly as spyware.
