Problem decoding frame-skipped video with ADV212

Our application needs to decode a compressed data stream at a frame rate below what the VDATA bus is being clocked at. We feed the decoder with compressed code for fields 0 and 1 and then wait about 40 milliseconds before the compressed codes for the next two fields are sent to the ADV212 decoder. At the start of decoding the VDATA bus outputs video frames periodically as expected. However, after a few seconds decoding stops and only black frames are output and it never re-starts decoding. I have tried different delays between sending the compressed codes and this affects how long the decoder runs before stopping, but it always eventually stops and never re-starts. Is there a way to restart the decoding without having to re-boot the ADV212?
