I need a cheap mode to record / watch multiple TV channel at the same time on a single PC.
Can anyone recommend me any solution(TV Tuner, Application) that can help me solve this problem?
I'd recommend SilconDust's HDHomeRun. It's slightly more expensive in comparison to internal PC cards, however it's an external tuner that you can hook up to your network via ethernet. It also has two tuners built in. It's extremely easy and simple to hook up. If you use something like Windows Media Center or MythTV, they both work directly with the HDHomeRun. I've only used WMC with the HDHomeRun and it was an absolute breeze to setup.
