DSR 4200 info vs 4DTV

[chuckles314]

Hi,
I just recently purchased a GI DSR 4200 do you know where I can get a remote control, and more info docs? Also can a GI DSR 4200 receive the same as a 4DTV (DIC2 clear) or is the 4DTV (905,920,922) a better unit (more worth while)?

A second question, is a PowerVu 9234 worth looking into for clear feeds?

Thanks.
Nice site good info.
