Hi i have a crown cdv 661 dvd.i am converting avi to mpeg1 with tmpg.enc and authoring with vcdeasy.if i burn the film onto a phillips cdrw or a tdk cdrw it will play fine.but if i burn onto a cdr(verbatim,intenso and acer have been tried) all i get is a no valid disc message.i have made a direct copy from cdr to cdrw and it played so i dont think burning speed or program bugs.can anyone recomend a tried and tested cdr and possibly a source accessible in uk.thanks in advance.
