I've got a similar set up and use lossless transcode, It reduces file
size by ~15% and is very fast. I did try transcoding to MPEG4 but those
pesky blips and glitches cause the audio/visual sync to gradually slip.
Wrecked Mary Poppins and I had to wait months for it come around again.
Commercial detection would be great if you can do it but changing the
right/left buttons to skip 29s is pretty good (those commercials are
charged by the microsecond so they get exactly what they pay for).
