Sony MP3 NWZ-A818 Video Playback Problem

[Skipp]

Hello all

I just purchased one of the new Sony walkman mp3/video players but I have run into a problem.

In order to get a video file to play on the walkman it has to either be in the mpeg4 or H264 AVC/Mpeg4 formats. Iam using Total Video Converter to convert the videos I want on the walkman. The problem is that after conversion and imported to the walkman hardly any of the files will work.

The files show up in the walkman menu with the relevant length of time displayed but when you attempt to play them it displays a message saying this format is not supported.

So is it the walkman or are some video files even after conversion just not foing to work for some reason ?

Any help would be appreciated

cheers

Also are there any good sites out there for mpeg 4 videos or is there video conversion tool that will do the job better out there
