Thanks for the file. Have you tried editing the file manually and importing it back in the TV?

In the attached file I swapped Das Erste HD and ZDF HD so that they have numbers 2 and 1. Can you please try to import this list and let me know if it works as expected? sdb_65xr70_20240615-swapped.zip

Thanks for the respond. There was no error while import, but the channel order remained unchanged.

I did another export with manual moved channels on tv and now a differences can be seen from line 4469 onwards: sdb_65xr70_20240714.zip

Looking at your new files, I noticed:

• both new lists, the sdb.xml and sdb_edited.xml now contain "SERVICE_LIST_CABLE/4", while the original file 20240615 was ".../2". (I guess every time you run a scan, the number increases)
• my manuals changes in the readable part of "...-swapped.xml" are identical to what your TV exported in the "..._edited.xml" file
• comparing your sdb.xml and sdb_edited.xml, lines 4469 and later are part of a base64 encoded binary data block. I decoded the \, \
  and \ XML elements to .bin files, which seem to be serialized Java object streams. Those can't be decoded without the Java .class files that are part of the TV's firmware. Also, inside the service_database data, there is data compressed with MediaTek's proprietary "cl_Zip" format, which is undocumented and can only be decompressed by MediaTek software (i.e. the TV's firmware)
• the "summary" and "scan" parts are identical between the sdb.xml and sdb_edited.xml, but the "service_database" changed massively.

I have no idea why MediaTek is even bothering with exporting readable XML data, when the import only seems to cares about the binary, more or less encrypted data.

I'm afraid we hit a dead end here.

Thanks for your time and looking into it!

No new scan was made, only the channel lists were imported/exported via USB. As a test I also imported the sdb.xml with increased “SERVICE_LIST_CABLE/5”, but channels remained unchanged again. And finally I tried an import without the “service_database” block, which ran into errors as expected.

Too bad, but then the only option is to edit it via the mobile app: https://www.sony.net/channeleditapp Sync from app to TV over Wifi - is it worth to sniff the network? If not, then I think we are done.

Finally, if it is not too much effort, we will probably only have the option to make the sdb.xml of new Sony models readable in ChanSort so that we can transfer them to other TVs.

Read-only support should be possible.

Also thanks for the link to the mobile app. I'll try to get some insights from how it works.
