My previous set up was a 510 DVR with a Single LNB BS1H1UP201M, with only TV Globo a la carte. I am currently living in an apartment without Dish access, but will be moving this month. I would like to replace the 510 with a 921 that I own, keeping only TV Globo and using the 921 for OTA HD. Will this setup work with my current equipment? Will the BS1H1UP201M, which has two coax outputs, enable the 921 to watch one channel and record another at the same time?( I may add another Brazilian channel a la carte). Can I use the 921 on Dish without paying for HD programming? Will the 921 record OTA HD programming? Thanks for a great site!
