None of my boxes will show 4:2:2 feeds but last night I recorded one then put my hard drive onto my pc, I opened the recorded file and it played fine, which begged the question, if it's just a matter of a software upgrade, why don't more boxes support 4:2:2? I only know of the AZ box but thats expensive.

Well spotted. I didn't know you could do that - a lot might find that very handy even though it won't be live. What did you use to play it back.
You can do it on Linux receivers tx'd to a pc - very similar method really but then it's live & most PC cards just do 4:2:2 - even a basic USB Skystar - it's just not required for mainstream use on stbs re costs because I don't think it is just software ... a PC is more versatile for any resolution & colour depth so then it is just software & since you recorded the stream all the info is still there.
Great find!.
I used VideoReDo to play it back, VideoReDo is editing software which I use to back up files and take out adverts, it also converts files so I'm going to try to convert a 4:2:2 file into a .mpg file and see if it'll play back on my sat box.
4:2:2 is an mpg file.
Receivers wise it is nothing to do with software, the decoder chips simply don't support it.
I know it's a .mpg format but my box records in .ts format, so I'm going to try to convert it back to .mpg and see if anything happens.
It won't make any difference, there's no difference in the mpeg contents between transport stream and programme stream containers. Conversion without recoding is as fast as your PC can read and write data.
To get full details of the actual content open the file in Medianinfo and select tree view.
It will be, there's been feeds in the past that I've ignored due to it been in 4:2:2.
