why m i not able to watch the old episodes

hey guys i m very new in this site and very thakful to u all or all of the episodes of ramayan but i hav one question why m i not able to watch the old episodes from the link provided will u please help me in this

they might have expired.....but you can watch them on youtube too now, user SagarArts has uploaded most of the videos i think.....or a better alternative is BigFlix.com!!!!!!!! there all the epis of Ramayan is uploaded with clear cut quality and no ads...thats the best part!!!!!😉

Bigflix is where to see them, but downside is that they cannot be downloaded unless you buy (and I' ve had viewing problems in the last few days even under IE/Windows, where audio comes but video doesn't). SagarArts in YouTube has uploaded the recent ones and is pretty regular about it, but the first half of the serial hasn't been uploaded. Some old clips are there under various users (Rupalip & Vrishasena), but no comprehensive collection of the older videos.

I'll find out from SagarArts whether he plans to upload the older episodes once the complete serial is over.

thanks guys u are really healpful
ok i will check in youtube and see
