I have been experimenting with different TV tuners and broadcasting options that I currently have access to.

Asus MyCinema EHC3150 so far I have had great results with this Card for TV but when I started streaming to veetle or any other streaming sites applications my input size is very small 352X288 that is it no secondary options now obviously when I broadcast that as soon as you start to enlarge the output the distortion gets out of control fast. I wasn't sure what was causing this if it was software related or hardware related so I purchased another TV Tuner locally. This time I purchased the PCTV 800i much to my surprise input size was larger 720X480 this does allow me a larger picture with a higher quality stream.

Now what I'm really trying to figure out is how can I find out the max input size for a TV Tuner before purchasing it? Does anyone have a TV Tuner suggestion that provides a larger option of input sizes? Or does anyone know how I can find out what input sizes will be available without buying cards and sending them back as they don't offer anything better then I currently have?
