Thanks Sir, just like you've said, I also googled that query, and hindi ko po nakita answer sa net e, misleading sya actually.
To make my query short
Are 50gb version better than the 25gb version BD's in terms of PQ?
Like dvd's, dvd5 are compressed compared to dvd9 version, lalo na kung more than 2 hours yung film.
Are bluray discs like that po?
