[Live-devel] [Fwd: Re: trick mode index files: x86 and ppc]

[Daniel Robbins]

Ross,

I've confirmed that the indexer was run against identical .ts files. 
These .ts files were created by the testMPEG1or2ProgramToTransportStream 
executable, run once each on x86 and ppc. However, the resultant .ts 
files had identical md5sums, so no problems there.

The indexer did not produce identical .tsx indexes from the identical 
.ts files - the resultant .tsx files differed by small values in 257 
distinct locations. The binary difference between the differing bytes 
ranges from -1 to +3, if that helps.

Regards,

Daniel
