Playback Split Screen problem

[stryder]

I have got a strange error on playback, it only occurs on recordings for a specific UK Channel (E4) , the playback splits the screen , so you get a black vertical line down the screen (about an inch thick) at say 75% to the right and the 25% that should be showing to the left is now in that 25% at the right, it basically looks like the screen has been scrolled to the left with the left hand side wrapping around to the right,.
This only occurs when playing back recordings made on E4 channel.
Viewing the channel via my built-in TV DVB-T tuner is ok, and even using the rescan tool in GB-PVR, the picture looks fine when viewing the channel in the scanned list.

I checked the recording in Media Player to see if it was a tuning problem, and it plays fine.
I made sure all FFDShow post-processing was switched off incase that was affecting it, have tried different decoders as well, to no effect!

I can only assume it is a combination of some artifact in the Recording and the decoder?
I thought maybe it was an issue with my Graphics card (ATI Radeon 9550), but all other recordings are ok.

The recording is made on a dual DVB-T tuner (Nova-T 500), I have tried each tuner. , same effect, I am storing the recordings as dvr-ms.

I am running the new version (1.3.11) but only upgraded yesterday, and was the same on previous version.

Anyone else seen this, or have any ideas as to what could be causing it?

Sounds like its your decoder causing this. Try a different decoder.
