Why not just use ttpci-bwlimit.diff to patch the driver? There is also a patch floating around that lets you select what to block.

Hi list,

One of the known problems of the FF-DVB cards is the bandwidth
limitation, that is addressed by the full-ts-mod for example. However,
there are still enough FF cards out there that are not and wont ever be
modded, and these cards tend to produce broken recordings on high
bandwidth channels.

I've written an experimental patch to avoid this by limiting the total
bandwidth of the DVB card for recording and playback. In case that the
bandwidth exceeds the allowed maximum, the playback gets reduced to
I-frame only, audio only or complete suspend. Recording is not limited.

The patch is still fresh and not well tested, so its only recommended
for experimenting. Also, there's only a VDR-1.6 patch now, VDR-1.7 needs
a rewrite for TS, and will follow later. For first experiments, set
Setup ->  DVB ->  FF DVB Bandwidth Limit (kbit) to something around
