No. You can make it usable. As I recall one of the "features" of the new and improved GUI of the aftermarket stuff was the elimination of BS from the menus, and prolly removal of the code for it in the FW altogether. (Signal thiefs have no use for BS on Echo birds) The new awesome, cool, rad, hip, WTF ever (crappy AFAIC) GUI was adopted overwhelmingly by the mindless "drink the Koolaid and look at the pretty colors" mentality morons that it was tageted for, AKA those Free(loaders) To Air operators from the dark side.
Put somethig pre "New GUI" on there and your BS selection will return. Be prepared, it is very slow.
The 2K (Platinum) was a 1st gen (actually the popular one was the 2nd version of the same named box) and the last of that design was the "Lite" that was a model stripped of some of the "unnecessary" (for stealing signals) hardware. It was the same from an OS position so the Lite FW also runs on the 2K Platinum. There is a 2K Extreme that does have hardware BS (still slow compared to a legacy Coolsat) and the FW is NOT intechangable with the Plat. Take care not to dl/load that Extreme ver on your Plat.
The AC3 optical out is all they came with. You still must run that to a decoder/amp to hear the AC3 content. Many of the later higher end receiver/amp have digital/optical input(s). If you dont have one, Google Sonic Voom. It is a compact AC3 to analog decoder, with headphones. The jack is proprietary for all six signals but a std 1/8" can get you an analog sound source to work with. Some have said there are "holes" in the sound presumably when the audio is on the channels that arent being connected to the amp. I had considered cutting the connector off the headphones and building a resistor network to re-mix all the channels back to 2 input mode, but my stereo has AC3 in so it hasnt been a priority project.
I think I paid ~15 buck for the lil thing via Fleabay a few years ago.
The Viewsat is a mediocre box in the world of real FTA, but it makes a decent receiver in a dedicated set it and forget it service, like for the grandkids, the elderly etc. If anything else you use is supported by the ChannelMaster editing app. use that for scanning as opposed to the VS.
For example, the neat thing about using the ChannelMaster software and a Coolsat 6K is that I can scan in everything (SD) I want to have, load it to CM and output a .cha file compatable with the VS.
I believe Iceberg posted the OEM FW for that box a year or so ago. There isnt really a files section here per se, you have to look thru the posts for attachments. I'll see what I can find, but the post search GURU is Anole. If he can find a link to what you want, it doesnt exist.....lol
