Thanks Posde. From what I've researched (read from google searches) the problem is the library files not having the latest version of AAC due to licensing restrictions. So it should only be the library files xine uses for it's codecs that need complying rather than VDR. Viewing the recorded VDR files direct in xine shows the video fine but no sound, hence my thinking it's libraries missing codecs rather than VDR or xine requiring compiling as newer versions. I'm still getting to grips with how this all works so I'm not making a statement, I'm looking for confirmation that my assumptions are correct that it's the libraries FFmpeg or FAAD that are the problem. Thanks again for your time.
