1. garbage in, garbage out.
i.e. if u play small low grade files, it does not matter - u get same crappy video and audio.

2. tv makers do not make/oem the best players, not their core biz.
still, rm20k 4khdrtv probably give better results than rm2k 4ktv.
cheap tv players will give issues like format type, subtitles, fast fw/rwd, aspect ratio, frame rate...

3. old boxes like yours can't do many things... 4k, hdr, 10bit, h265, ddtatmos, dtsx, etc.
but again, if u play simple files, not an issue, can use.

4. it's always about budget vs purpose.
u can spend rm2k for some player or rm600 or rm200 for another.
decide what u want to play, how good is yr display or audio system, then buy box player accordingly.
just dun spend rm30k for tv and home theater only to play low grade files with the lousy player in the tv or in an old box.

in this scenario, the diff may be small, but still noticeable to discerning eyes.

there are box players rm500-600 that will do a better job - video, audio and other features.

of course, u can spend rm1k, 2k, 3k too.

your old himedia is likely q5 or q5ii, can still play your 1080p files... use it, compare.

but having 3 models myself, i can tell new models do much better - more vibrant colors due to better engine, smoother due to autoframe switching.

if himedia, go for q10pro.

u will be awed if u play those 70-90gb ones.

yes, HDD cost money... so... keep only the best ones, the ones u will play again in the future.

These biggies are full ones... check the bit rates when u play them... they are anything... 50, 70, 90mbps... u can calc the toal GB!

And yes, they incl multi audio tracks, all the subs, extras, the making, etc.
