Oops. My bad. I had assumed we were talking about High-Definition content.
I took a look at the
specifications of the DISH Player-DVR 625 and noticed it only has Composite and S-Video outputs. The Hauppauge Colossus won't work for you as it only accepts HDMI and Component inputs.
Pretty much any video capture card that accepts either S-Video or Composite connections should work. As to your questions:
Anyway, when we do the real recording, are we still be able to view the contents on the TV set since we have to direct the output to the capture card of the computer?
Yes, you should be able to still view the content as it's being recorded, however, it may require the use of the second tuner (see below).
In addition to that, is it possible to record a movie (like old movie) while watching another channel like sports at the same time?
The specs of the device state that is does have two tuners. I assume the connections would be something along the lines of TV1 output to your primary TV and TV2 output would go to your PC. Note that I believe this requires the use of a special remote control. The two tuners work independently of each other, so you can have one channel recording (movie) while watching another (sports).
I would prefer to record two or three channels at the same, not sure if that is also possible.
Sorry, but this is not possible. Since your set top box only has two tuners, you could (theoretically) record two channels, but this would require two video capture cards and probably two PCs
