There is a bug in the DM7025 generating the txt-tv signal for the TV
(The generated signal for using txt-tv on the TV it self)

For most channels txt-tv signal are working just fine after Enigma2 is up running.
But some channels are failing the txt-tx signal for the TV.

When it's failing will it do fail on all channels.
If you restart Enigma2 the channels that where ok in the first place will work again.

When it failing can you also see in the txt-tv upper line, that it's flashing fast between new and old txt-tv data ?
It seems like the software don't clear the memory from old txt-tv data.
It's mixing new and old txt-tv data ?

Here is what to do for getting it fail:
--------------------------------------------------
1) Restart Enigma2

2) Goto e.g channel "ZDF" at 19,2 east.

3) Now press TXT-TV on your TV and you will see all is OK.

4) Goto channel "MTV germany" at 19,2 east (IMPORTANT THAT IT IS THIS CHANNEL) Some others also fail, but this one is good for testing.

5) Go back to channel "ZDF" at 19,2 east

6) Now press TXT-TV on your TV again.

We now have a txt-tv signal failure to the tv, that will continue on all channels.
