Couple of suggestions for future VDR packages:
#1 Split runvdr to two files: one for kernel series 2.4 and one for 2.6. Current runvdr needs to be modified before it is usable in 2.6.
#2 Separate config file or additions to Make.config for things that are configurable (e.g. MAXOSDMEMORY). Modifying of source code is not good practice.
