Why are my SD recordings file size the same as HD recordings

September 18th, 2009

Most Set-Top-boxes (STB) includes an option to up-convert any content to 1080i or 720p over component cables. Enabling this feature will make the STB always send HD content to the acquisition device, even for SD channels.

To change this behavior, verify your STB configuration using your STB user manual.
