I have a comcast DVR and I want to put stuff up on youtube, but I dont know how. What cables do I need or what programs do I need? Any help would be great! Thanks in advance!
You will need a TV tuner card such as a Hauppauge WinTV GO, connect the cable box to it, install a TV tuner program on your PC, put it on channel 3 (or Composite or S-Video if the tuner card and the box have composite or S-Video), and then record.
For Windows, WinTV GO comes with WinTV 2000. It allows you to watch TV and record TV. I prefer using the InterVideo WinDVR 3 program to watch and record TV.
For Linux, the only worthwhile TV recording software is MythTV. There is also Freevo, but I have never been able to get it properly running on Ubuntu. (Freevo is also available for Windows.)
For both, you can use the VLC media player to record TV, although getting it set up with your TV tuner on Linux may be complicated.
If you have a Mac, you could get a firewire TV recorder and use Final Cut Pro.
