I notice that SDTV subchannels rescale slightly when launching. I can receive some on my HDHomerun networked tuner, and play back on computer using mplayer. The diagnostics from mplayer include...
I leave it at 704x528 on my notebook (1366x768 display), and double up each dimension to 1408x1056 on my desktop (1920x1200 dsiplay). Both machines are linux. So far, I've confirmed this on NBC Universal Sports (2.2 Buffalo), RTV (2.3 Buffalo) and TCN (29.2 Buffalo). WNED and WNYO aren't coming in for me tonight. Anyone else notice this rescaling? How about SDTV subchannels from other cities?
