What fw did you use for the upgrade?
It seems you used a wrong one or something went wrong during the upgrade.
@to all:
I found on a finnish forum an official update for the dbrh-198: fw 60820c - stb 4.0.2.11, which supports MPEG4 recording.
An australian user succesfully tested it (only the main fw not stb) on his dbrh-1979 (which, as far as I know, is similar to the dbrh-197 but with a 250gb HDD).
I'm not sure it is suitable for your dbrh-197, so I take no resposabilities!
Who will decide to perform the update,
will do it at his risk!
Here the
link I found.
I think that, for the ones who want to take such risk, it is advisable to perform
ONLY the upgrade to the recorder fw (main fw)
NOT to the TNT fw (stb fw), to avoid to damage the digital tuner.
