Online videos hanging could well be to do with your connection to your provider. When watching a video that starts to hang just click the pause button for a few seconds to allow the buffer to build. You should see the cache continue to build then click to play again. While it does not correct the DVD problem you might consider an external DVD player/burner. Some listed below to give you a price spread. Did you try anything that Bob suggested above? Is the Time Warner program a full anti virus and anti malware combination or purely anti virus? Here is a link that might be useful: Sampling of external DVD player/burner

DVD players do not have tuners which select stations, so there is no need to supply them with a signal from an antenna. It can't do anything with it. Your DVD player only sends a signal out. Can the TV handle both the coaxial antenna from the cable box and the yellow/red/white RCA cables from the DVD player? If it can, your problem is solved.

Could be dirty optics lens. Radio Shack or most electronic stores sell cleaning disks. Try one. pw

I've never had any problems with any of my Current DVD Players, playing any DVD's (Newer or Older). We have 2 x Sony 5 Disc 5.1 Surround Sound Systems (All-in-One) and a Philips DVD Player, all are older units, nothing New. None of these players are capable of playing the Blu-Ray Discs! Many, Many years back, we had a GE DVD Player (our first DVD Player). We ran across one DVD, that no matter what we did, it wouldn't play Disney's "The Kid" with Bruce Willis. This was a Brand New DVD Player and the DVD had just been released. We retuned the DVD 4 x before finally giving up on it. I even went as far as taking the GE DVD Player to Wal-Mart, so they could see that the DVD wouldn't Play. It played on the (their) Same Model GE DVD Player on the store shelf, but wouldn't play on mine. This DVD Player was a Gift and wasn't purchased at Wal-Mart, so I couldn't return it to Wal-Mart. Never did try returning it, it played every other DVD just fine! We do however have an LG Blu-Ray Player that we just started using this past summer. Hooked it to my New Sony 5.2 Surround Sound Stereo Receiver. We also have 2 Sony PlayStation 3 Gaming Consoles (1 x Fat and 1 x Slim) that have Blu-Ray Players Built-In. BTW, Blu-Ray is Backwards Compatible and will play all your DVD's.
