lowres should work with wavelet codecs
for h.264 there likely would be problems due to intra predicton possible 
solutions would be
* use small slices for i frames on the encoder side and limit the amount of 
  intra allowed in non i
* decode intra blocks at full resolution
* let encoder run a normal + lowres decoder for all decissions like intra 
  prediction direction
