Connecting to a tv without a hdmi port

An HDMI to Analog (Composite Video, Stereo Audio) adapter will work fine. However, it has limitations. You are forced into 16:9 widescreen anamorphic mode. This is fine if the program is widescreen to begin with; it will be letterboxed on a 4:3 CRT. But if you are watching native 4:3 programs, it will squeeze the square image into a rectangle with black bars on the sides. You are also limited to stereo because analog outputs can't carry a Dolby Digital stream. If you get an older Roku with analog outputs, you can change to 4:3 native output, everything will display correctly and skip the HDMI adapter. But that introduces some other limitations such as price, menu slowdown, and/or streaming channel compatibility.
