The index file uses 8 byte per entry, two of which are now used for the file number, one bit is used to identify "independent" frames, and 40 bits are used for the actual file offset. The remaining 7 bits are reserved for future use ;-) 40 bit allows access to 1TB, which, assuming 2GB per hour (for current SD recordings) means a single file recording can be some 500 hours long. That makes 20 whole days in a single recording. Ok, let's assume HD recordings need like 4GB per hour, then you still have 10 days in a single recording. If you actually have a need to record more than that in one single recording, we can use some of the reserved bits to increase that number ;-) Klaus _______________________________________________ vdr mailing list email@example.com http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
