Every time I've had an issue with pytables reading a non-pytables created file, I've submitted a bug and it got fixed usually in a few days. At the time, I was using HDF5 as a transfer layer between matlab's rudimentary hdf5 support and python w/ pytables. (Thanks Francesc!)

PyTables will automatically add it's own metadata, which is something h5py won't do - if you care.

Best,
