h264fhdvenc(version 01.10.02.05) simultaneous encode + decode supported for 720p and below resolution

Hi  TI experts,

               Lately,I encounted two problems when I test the encoder/decoder applied by TI for DM6467T. The encoder/decoder's version are follow,

h264fhdvenc                01.10.02.05

h2641080p60vdec     01.20.00.14s

             One problem is that h264fhdvenc's releasenotes  write like this

SDOCM00057668              Simultaneous encode + decode not supported because both HDVICPS are used by the 1080p encoder           DM6467_BP_001

 but no similar description for 720p and below resolution. And The programm went to deadlock when I tested Simultaneous encode + decode  for 720p and below resolution. So I cann't conform whether the encoder h264fhdvenc supports simultaneous encode + decode for 720p and below resolution.

             The other problem is that  the encoder went to dead  after running about  35 minutes when  only  running  the encoder(h264fhdvenc  01.10.02.05)  but not  decoder. The demo and application are like this. So I want to know whether the encoder  need  register  or   charge .   

             Hopefully  TI experts can give me the answers about   two problems above as soon as possible.    

Thanks.

Best regards,
