For playing Bluray on a HTPC, is there any advantage of buying something else than the lowest priced drive? Since all the decoding is done by a Bluray software (like TMT, PDVD…), can a high end drive give me a better experience than a budget one?
Generally, the higher price points are due to more features such as higher reading/writing speeds, extra capability such as BD writing, retail packages which may include extras such as cabling and software. If your goal is simply to read the disc while watching, the lowest cost option should suffice.
If you are ripping discs, you may want to pay some heed to the read speeds (e.g. 12x will read faster than 10x). Also, some drives may be noisier than others.
