---> I have the DST51 so I don't know about the DST50. I have owned the DISH 5000/HD mod,DST51/HD1000 for nearly a year so I am quite familiar with its operation.
Does the TU-DST 50/51 have component outputs or only RGB Output Jacks (with H & V sync) which require a transcoder?
---> DST51 has Component Out , NO rgb.
Does the DST50 and/or the DST51 have DFAST protocals? Should I care?
----> Neither do. The DST51 has 5C but no one knows whether it really works. Search for Posts from Don Landis on this.
Does the DST51 have unconversion from 480i/P-720P to 1080i that the DST50 does not?
-----> The DST51 has a switch on the back for 480/1080,480 or Native. When set to 480/1080, 720P programs are downconverted to 480P. Not sure about 480I as I have never seen the point in recording such a c***py picturehttp://www.avsforum.com/ubb/smile.gif
Does the HD1000 have copy protection of any kind? Will it record and play a 5C encoded program?
----> Don Landis had a series of posts about this. I can not remember what he said and since my system has never 'seen' 5C data, I do not know.
Does the HD1000, when used with the Dish 5000 for HDTV recording, have the capability to record and play DD 5.1 Channel Digital Audio through the TU-DST 50/51- or- does it only have VHS Hi-Fi Stereo Sound?
----> Don't forget to add the DISH HD modulator. The HD1000 will record the DD 5.1 audio just fine as it is bascially a 'bit bucket' when connected to the DST51. The DST51 does the actual decoding of the data coming from tape.
Does the DST51/51-HD1000 have audio drop outs, when used with the Dish 5000 for HDTV recoring and playback, and require the Technics AC500 decoder?
-----> NOT on my system which is the Yamaha DSP-A1 so I do not need nor use the Technics decoder. There are posts regarding some receivers that do not work perfectly.
This is assuming you are using good quality S-VHS tapes.
I am sure someone will chime in and add their 2 cents.
The 720P downversion always seems to get argued about but MY DST51 DOES downconvert to 480P. It is visually obvious because I also have accessDTV which upconverts EVERYTHING to 1080i if you tell it to. In my area, 720P only applies to FOX and ABC. DISH does 1080i ONLY.
