If you mean choking on feeding -ao/-vo mpegpes that could be just as much 
because of the vid mem size in newer firmwares to be honest.

As Klaus says "there's a life after 1.2.0" :).

I believe there's some CRC32 checking code in mpegtools ( 
http://www.metzlerbros.org/dvb/index.html ) maybe that can be used.

If at all, it should only be done on recording as transfering to say an 
av7110 or dxr3 they have their own means of dealing with broken streams in 
a less interruptive manner than just throwing the packet away? But then 
again broken reception crashes the decoder after a while more often than 
not. On full cards in live mode not a lot vdr can do against it?
